****ed off soon to be ex client

i wish there were zero stars, i bought a new car and netstar updated their system with the new information. i was provided a letter confirming they have cancelled service for my old car as i no longer have it. NETSTAR decided to reinstate the car that i do Not have and charge me twice for over 20 months., when i reviewed my statement they claim the car was cancelled but reinstated. this made no sense, i have a CANCELLATION letter from Amogelang Mokhonoana confirming the cancellation. now i am calling back and they keep giving me the run around, the worst person i delt with was Thabo N from retention who does not return calls, keeps making promises, clearly clueless. he is a **** and not trained unless its that's companies culture. i am now holding the line for more that 20 min lord knows for what. their investigation cannot take more that 2 weeks. this lady is asking me the same think and i have to repeat my self to every representative that come on the call. i wonder what management is doing is there types of error happens and they don't pick them up. I WANT MY MONEY BACK.. SIMPLE . You can also cancel my service, you are not the only tracker company out there. what a horrible service . i am sure this did not happen to me. people need to check their statements parodically, clearly were are dealing with *******.
