Don't let them touch your Luxury Car

on the 23rd of April they came to de-install my DQ track out of my BMW 3 series, they removed the unit but didn't return my car to me in the same condition, when i notified the technician he assured me he would come back and repair the de installation, i have kept calling and now he doesnt even answer my calls, when i notified Discovery the agent told me that they can only come out on the 2nd June??? WHAT?? more than a month with a broken luxury car? how is this possible?? the attitude of this employee leaves much to be desired by a Client, telling me i was wrong, and the alleged damage to my car? tell me something if BMW confirms that the tracker was installed where the damage is as the wiring is still there.. now how else would that happen? should discovery not make a attempt to rectify this matter by the end of the week i will be taking the car to Bmw to repair and their estimate is R4500 to repair with the bill being directed to Discovery, as well as broadcast my dismay with every social platform available.
