Very disappointed

I reported my unit to cartrack customer service in October 2020 that the panic button was not functioning and the customer service promised to send a technician. Ever since then i kept calling wanting to find out the outcome but they'll always tell me they will call me back after they locate a technician but they never did. Then i stopped paying thats when i started receiving calls asking me for payments. Ever since then nothing happened until i had to dind another tracking company. Now i find out that i have been blacklisted due to none payment but how do you pay for something that you don't benefit from. I am very disappointed and i will never advise anyone to join cartrack
