What a bunch of ........

I had a Netstar in my car which I sold 2 years ago. When I bought the new car I cancelled the old contract (Netstar refused to transfer it to the new car) and paid a cancellation fee !!!. Now 2 years later I see that I am still being charged for the old car. On enquiry I was told by Kabelo from Netstar that when I cancelled the old contract Netstar did not cancel the backup unit of the old car and hence I am being charged. Now because Netstar has not done the job properly in the first place, I am told that they can cancel this backup unit, however I have to pay the cancellation fee, or continue paying the monthly fee. I was told by Kabelo that I manager will call my as I complained that it took them 30 minutes to answer the call. I AM WAITING PATIENTLY but I know it will not happen.
