Ha pasado ya más de 6 meses y sigo “esperando” mis certificados, son 5, se molesta si le preguntas o le pides explicación argumentando que “no es problema de él que revoquen los certificados” cuando es la única persona que vende certificados que primero cobra y luego no da la cara, compre otro certificado y hasta ahora no se a revocado, tampoco tengo que “dejar de actualizar mi dispositivo” a la última versión de iOS o tengo que hacer un procedimiento extraño para firmar aplicaciones, si no sabes cómo solucionar el problema simplemente retírate y deja de estafar a la gente @iammanpreetsingh

SCAM! certificate revoked immediately and owner blocked me
DO NOT WASTE YOUR MONEY. This is a complete scam. I purchased a certificate from AppTesters.org on Wednesday, July 9, 2025. After waiting for a long time, it finally arrived on Friday, August 29, 2025.
it was revoked the very same day I received it, before I even had the chance to install it. Despite their terms of sale clearly promising a free replacement in case of revocation, I have received absolutely nothing. Since that day, there has been no communication, no refund, and no replacement.
When I tried to ask for what I paid for, the owner (Manpreet Singh) simply blocked me and I was permanently banned from their Telegram group. They take your money, provide a broken service, and then silence you so you can't complain.
It has been nearly a year of silence. This is a fraudulent business. Avoid this scam at all costs!!!

Esta compañía es una estafa total
Esta compañía es una estafa total, pedí un certificado premium de 25€ hace un mes y todavía no me ha llegado. Además el soporte me ignora, mandé un mensaje mediante la web hace 2 semanas y no he recibido respuesta alguna. Estoy pensando en una devolución y tomar acciones legales u económicas.

Certificate fraud by appletester.org(manpreetsingh)
After various massages and emails asking for explanations, and in the end asking for a refund, after buying various certificates and skipping the line paying several times I realized that I was being scammed by manpreetsingh and his appletester.org
And I was deleted from the telegram group without an excerpt of motivation.
I do not recommend the purchase of future certificates.

DECEPTION
I want to say that I am shocked by everything I have experienced with apptesters.org, especially from the owner, Manpreet.
Before I begin presenting the facts and criticism, I want to emphasize that I am extremely disappointed that a service which used to be one of the best has turned into this, and the only word I can use for it now is deception.
I ordered my first premium certificate from them in October 2024, and I had no issues during the first year. When it was time to renew the certificate, the new certificate got revoked immediately. I personally explained to Manpreet that I needed a reliable certificate and that I could not afford to wait on a list, where I was placed around position 3500. He offered me a discounted Premium certificate, and I accepted so that I would not have to wait for months for my UDID to be processed. However, even before the certificate was delivered, it got revoked. I informed Manpreet about this, and on November 20 he personally wrote to me on Telegram: “Tonight, I will add all pending UDIDs for processing.” Of course, he did not do that. I ended up waiting more than 85 days, during which he kept telling me that they did not have enough developer accounts to process UDIDs. At the same time, I mistakenly received an email from them offering me a new certificate at 50% off.
I contacted him on Telegram and asked how that made sense, that long-time customers who had been waiting over three months for what they already paid for were still waiting, while new customers were being offered certificates at a 50% discount. He was very rude and impolite. His explanation was: “that email was first of all never suppose to get to you. it got to you because your udid was revoked. but we sent to you by mistake.” He also told me that he would have my UDID processed BEFORE January 20 (this conversation took place on January 17, 2026).
When January 20 I asked him what was going on. He attacked me and claimed that he never said BEFORE January 20, which is completely untrue. Not only that, but when I questioned him, he tried to insult me by asking whether I suffer from depression, which is absolutely unacceptable and a very low blow. Even if I did suffer from depression, that is not a way to insult anyone. He finally processed my UDID again on January 21, and once again the certificate was not delivered because it got revoked before delivery. In our conversation, he also stated that regardless of whether he was wrong or not, he would always defend himself.
Manpreet is someone who cannot tolerate any criticism, not even constructive criticism, and he reacts aggressively and resorts to low attacks. After sending several messages to which I received no response for days, I decided to leave a negative review , similar to this one, with a detailed timeline explaining everything. He immediately deleted my review and banned me. I emailed multiple times asking why I was banned, but I never received a response.
I am now requesting a refund, since I never received the service I paid for. He doesn’t respond. I do not recommend that anyone do business with these scammers , not only because of the terrible service, but also because they feel entitled to insult someone by implying they suffer from depression simply for asking why their UDID was not processed when he personally said it would be.
This kind of behavior is outrageous. Despite having every reason to do so, I never insulted him in any way during this entire time. All of our conversations have been documented and recorded using a screen recorder.

Absolute Scam
Manpreet promised to give me a new certificate after my original one was never delivered for an extra 5 dollars. After paying, I was left on read, and was not in the queue. This is a scam, and I recommend KravaSign. I got an instant certificate from them, while AppTesters never delivered after a promised 3-4 day processing time.

scam lol
i bought a certificate for iPhone, choosing the premium plan for $25, with a promised warranty. I waited a week for it to be made, after which the certificate was revoked just a week after creation. Despite having the premium plan, which promises "full revoke protection," no one wants to deal with the reimbursement for a new certificate.
