Pathetic service

Bought a car from Mobilis Kempton park a month ago, noticed within a week that there's a funny sound on the car which I reported, was advised to bring it in to get it checked and fix it since its under warranty. I took my car to their dealership, since then they don't communicate, when you call to do follow up they send you from pillar to post. Now I have to run after them ,they are busy chasing new clients. Their service is disgusting they don't care about their customers. The service you receive when you buy the car and after you have bought is totally different. Now I have to Uber to work what an inconvenience.
