Dishonest Tracker Service

I am in the process of buying a new vehicle, and wanted to transfer my tracking unit from the old vehicle to the new one, called the call center to arrange it, only to find out that the old unit is useless and must be discarded,and the contract must be canceled. New unit must be fitted to the new vehicle with a new contract at a cost of R1195.00, this was not explained to me at the start of the contract. This is ****************.
