Incorrect information suppl****

I purchased a new vehicle and requested that my current tracker be moved to the new vehicle, i was advised that they no longer do this and they will install a new tracking devise. I was given the monthly premium. I gave the vehicle details, confirmed banking details. I also requested that a second devise in my Yaris be tested but this was never done. After I finished my call with Norman I received a call back from him that he spoke to his manager and the cancellation penalty would only be R200.00 This month R714.06 went off my account. Kgmotso was most helpful and advised that the penalty was R400.00 and she explained that moving the unit would have cost more. I did advise that I did this before and I was not charged for it. I have requested that the calls be pulled so we can confirm. I feel it is a bit unfair that I have to pay a R400 penalty fee, a further R198.00 cancellation fee, R20 pro rata fee (as advised by sms) and the cost for the new unit. I have been a client for many many years. I don't even know if the unit in my Yaris works. I am seriously considering cancelling everything with Tracker and going with a different supplier.
