Bad Attitude & Shocking Service (Non Service)

I have been a client of Netstar for many years. In Nov 2014 I subscribe to a 3 yr contract as this was a more viable option. In May 2015 we traded a Nissan in for a Renault Clio. I then arranged with G Motor Radio to remove the unit from the Nissan and install it in the Renault Clio at R1,300= They sent a technician out to do this on 19/05/15. After 5 hrs he said that he was done and I paid him R1,300.00 in cash. He tested the remote and assured us that the unit was working. We took delivery of the vehicle but noticed that there was a warning light on. We then arrangement with Renault to investigate. After resetting the computer system they said that this was cased by the technician when he installed the unit. I then contacted G M Radio and told Cheryl that there was a problem with the installation. They arrange to re-install. After this we still had the same problem. Renault suggested that the unit be removed and they will reset the system. I spoke to Julie from G M Radio and they removed the unit and Took IT. Julie arranged with me that she would sent a QA to investigate on the 2 June. No response! Not done! The system was re-setted and works perfectly. No Unit in car.
