Very bad customer experience.

On Wednesday morning I received a call via Whatsapp correspondence for a part I needed for my w204 320cdi. Mathew Minnaar called me and I requested the part wich he then quoted me on and said he has in stock as it's a very common part. Friday at 1:30pm I arrived at century city and spoke to Mathew who recognized me by the part I have enquired about.. He then asked me for the Vin number which I supp**** only to tell me he has no stock but Rola Mercedes Somerset had stock but they are closing at 4pm as he has called them before I left century city branch to verify time and availibilty. I drove through to Somerset but when I got ther they were closed at 2pm already.. I then sent Mathew a message telling him that I am not happy with the run around I have received from him and I told him to make a plan by Monday as I have now covered over 300km for a boost pipe. He then called me and told me not to threaten him. With no apology Mr Minnaar had me so irate that I swore at him over the phone and switch the call off. He had no remorse in giving me the run around and didn't even sympathize in telling me he would organize a part. I drive a 4.0 v8 and 300 km costed me about R500 in petrol. I am very unhappy about this as I've only received the best service from Mercedes Century city in the past. I'm very ****ed and I'm not planning on returning to century city Mercedes ever again. How can you fix this for me?
