Customer service responded quickly, I received my item soon after. Haven’t noticed an improvement yet but it’s only been a few days of using.

Hi Laura, I’m really sorry for the worry and frustration this has caused. I completely understand why you’d feel concerned when the tracking hasn’t updated for several days. Please send us an email at [email protected] with your order number (usually a 5-digit number like #00000), and I’ll personally look into the shipment status for you right away. I’ll do my best to check what’s causing the delay and help get you a clear update as soon as possible. We truly appreciate your patience, and I sincerely apologize again for the inconvenience. We’ll make sure this is properly looked into for you.

Unfortunately, my original order appeared to have been lost by USPS. I contacted customer service, and they were extremely helpful. Maddy, in customer service, got right on the problem and looked into the tracking. Since it appeared that the items were lost in transit they offered me the options of a full refund or a complimentary replacement for the items I ordered. I chose the complimentary replacement, since I am really excited to try their product. Thanks to everyone who helped me, and a special thank you to Maddy and Coney!

Initial shipping was quick and great customer service. Dog ate my device and the Cleriva rep Coney shipped me out a replacement no questions asked! Worth a go. Combining Novaflow with antihistamines and a corticosteroid nose spray has got things under control for me.
