My customer service was great really helpful and polite I was confused at first asking questions and he answered every one of them and made sure I understood everything and he even explained the process step by step what to expect the day of the installation for my device

Updated my review. There's was and miscommunication in the beginning. Things did end up getting squared away. I'm grateful for Guardian Interlock. The agents and workers are mindful and willingness to listen and correct. So that's why I upgraded my review. They fixed the problem. Thanks Guardian. Will recommend and have recommended.

Terrible. Do not use this company. I spoke to multiple representatives before I made any appointment, about the 0 installation and free month. That you wouldn’t pay anything down. They assured me multiple times this was the case, and I reiterated that, because I get paid a different day. I went to drop my car off, and went to pick it up after work. Waited an hour, for anyone to even show back up after I sat outside. Was then told I owed $115 for the labor. I was told by both, that they had negotiated and both agreed on what they had told me. After being there another hour and a half trying to figure it out, I ended up having to leave my car there, because I couldn’t pay the $115 until the next day, and they wouldn’t give it to me If I knew this, I would have scheduled accordingly. So yes, there are “hidden fees.” And this is an overall horrible first impression, not looking forward to having to deal with this for the foreseeable future. Go somewhere else
