Cartrack horrific service

I Bought a car 2 weeks ago, sold my previous vehicle to the dealer. Cartrack was briefed about the process and requested that they remove the old tracker from the vehicle at the dealer and install into the new vehicle. In the meantime i have been driving around without a tracker and my previous vehicle has been standing being ready to get sold!!!! It has been sent to the relevant department for installing 4 times already .....
