NO SERVICE/ BAD SERVICE

Cartack has no customer service/ communication I have raised multiple issues with agents always promising to get a senior to call back and resolve the issue its still not done. I keep sending mails requesting assistance no one answers any mails. The app is more offline that online without any communication from cartrack that they have system issues. Calls are placed on hold for 20min just so the next agent can drop the call on a customer. Cartrack always have some bad excuse for the bad / no service they have then they wanna still collect monthly payment and additional call out fees to fix they're faulty units and customers must just pay. I don't think that's fair towards customers
