bad after service from Auto Xtreme Ptretoria

Good Day. I would like to share my bad experience with Auto Xtreme, 426 Pretoria Rd/Silverton. I inquire 2.5 month ago about Chrysler Grand Voyager 2011 model. I received the reply but I said I will also look around a bit. I had numerous phone calls in the mean time if I am still interested to buy. Finally I come to Auto Xtreme and look the vehicle and decided to purchase. My bad experience started with finance manager Luis who made twice mistake in the contract with MFC-calling and messaging me numerous times like to urgent sign the documents which I did on Saturday morning. Following week I noticed that I have been charged in the contract for Tracker Installation. almost R.3000. I phone Tracker and they had no knowledge of any unit installation in my car!!! Tried to call Luis and conveniently he deleted his Whatsapp following week through we were communicate and never answer my calls after. That is *****. Until today I don't have any reply regards the money which should be reverse to me for not installing the Tracker. Also, the after sale service is literally not existing-I barely can get hold of anybody there. The sales person Jan who sold me the car is not even responding to my messages. I AM STILL WAITING FOR SPARE KEY AND IS AREADY 2 MONTH. The registration papers and new number plates I only received after 1.5 month. I wouldn't recommend Auto Xtreme at all and I just started complaining via Hello Peter. Next step is social media.
