Very Bad Service ***

I received an email from Tracker advising that unit in my car was not updating, then I called them and we agreed that it needs to be inspected. I took the car to one their fitment center for the inspection and when I asked the technician what was wrong he said it not updating but now it's fixed. On the following day I got an invoice from tracker for a call out fee mind you the unit is insured and no one from tracker had called me to provide me with the full detail of what the problem was but am already being billed. When I called the call center to further enquire the consultant (Prudence Mxhesho) told the she does not know why I was billed and why nobody had the decency to call me and provide me with the datail of outcome of the inspection but am already billed.
