Inconsistency with my account

I hate Cartrack and wouldn’t advise anyone to tack a tracker unit with them. You pay and it’s like they are working with ****mers. I have never skipped a payment but yet I keep getting calls and incorrect information on my account. This is so ****en frustrating and annoying. The accounts department is so useless and the system is outdated! This **** company makes me sick to the core !
