Poor Service Car Tracker

Good morning My Name is Sthembiso Masikane ‬ I have been a member of car tracker for a long time and I was a happy client up until now when I bought the new car and have my tracker removed from my old car to the new car but until now I'm still waiting for that device to be installed. The payment has gone twice from my account but no device installed, I have called 3 time, send emails and to try to arrange with car tracker when they can come but I got feedback that I will be called back but nothing. they promised that they will call me after hours to arrange installation but nothing except getting calls and emails for payment for the device that is not installed and I have already made payment.
