Poor after service experience

Hi There, It has been 3 weeks now since my wife and I am without a car. A car that we bought from WeBuyCars Brackenfell for work purposes but cannot use it for that function for the past 3 weeks going into 4 and still no solution to this problem. My car had been with the Euro Motor Clinic for the past 3 weeks and they also tried everything to get my car's air-con pump claim signed off. Euro Motor Clinic has been in contact with Kimberly from the claims department daily without any feedback from her to solve this issue. I spoke to Waynand Pieters on Tuesday 30 Nov 2021 and according to him, the claim was never escalated. He promised to get back to me, after 48 hours I never received any feedback from him, I tried to call him today and the phone went to voicemail. How long do I now still have to wait and be without a car which I have to pay for every month but not in my use? Uber is making more money out of me now and it is causing great disruption in my daily work and home schedule. I NEED YOU TO CALL ME, URGENTLY!PLZ
