Poor Service, **********, Rude Staff

I have had a terrible experience at BMW Motorrad Pinetown in KwaZulu Natal. I have taken my bike there 2 or 3 times and spent quite a lot of money on repairs and servicing. The most recent visit, I asked for a Gold Link chain & sprocket. My chain was replaced with something else that started rusting within a few days and the rust went onto the sprocket. I then asked for the correct chain to be replaced which was done nearly a month later as they were apparently waiting for parts. They did not replace the sprocket and said it was surface rust and would come off. I'm not happy but anyway I let it slide. I also paid for my neck bearings to be replaced. However the bike is not performing like a bike that has just had new neck bearings so I queried this and asked to bring the bike back to be checked. The chain is also loose after a week and they want to charge me to tighten it. I have to phone and email repeatedly and no one ever gets back to me. I leave messages and I don't get called back so I have to leave more emails and messages until someone eventually gets back to me. The receptionist NEVER passes my messages on. Today I phoned and I was shouted at by one of your staff called Kashveer Barak so badly that I was left shaking and upset. He was disgustingly rude to me. I am DISGUSTED and SHOCKED at the poor service I am receiving from a so called premium luxury brand such as BMW. I have been given the complete and total run around from start to finish. I am charged for parts to be replaced, but those parts are not replaced properly. I have been ********** and spoken to like *******. I'll never support BMW again if this is the type of service to be expected.
