Pathetic service

I had my tracker transferred to a new car. Except for charging R870 the service is pathetic. Firstly they only had a job card to remove it from my old vehicle but not to install it in my new vehicle...what do they think is a definition of a transfer. The most frustrating is that THEY gave the wrong VIN number (one wrong digit). Customer care could change it and it had to be referred to a supervisor to change. After numerous emails, calls, logged tickets I am still waiting for them to correct a basic thing, their mistake, and to send me a proof of installation. Pathetic.
