VERY UNHAPPY TRACKER CLIENT

I posted a complaint on Monday regard Trackers bad service. Tracker contacted me and said they would look into my complaint. Tracker then call me again on Thursday the 25th April 2024 on how they would resolve the problem was by getting a 5th technician out to put the 4th device in my car to have a look at the problem and moving the Tracker to a different position plus 3 month free on payment. I told the lady I dont want Tracker in my car due to all the problems I have had since the 18th March 2024 not working. and she said she would get back to me which has not happened. Today I get an Invoice with a total due for R1600.00 and don't know what Tracker is on about as I told the lady I am NOT going to pay a cent as I have had Bad service from the getgo. So Please what the hell are you wanting money from me for.
