Mercedes Benz wake up

I recently purchased a Mercedes Benz AMG A35 Sedan, after driving it for a few months I noticed I had a bubble on my right front tyre. I took the car to a Tyre fitment center and they told me I hit a pot hole. Although I dont recall hitting the pot hole I told them to order me a new tyre. They came back to me and informed me there was no stock in the country of that particular size and tread pattern, and I should contact Mercedes Benz for the tyre. Unfortunately Mercedes Benz also did not have the tyre in stock and gave me a option to use a different tyre however I must replace 2 tyres at my own expense R5500 each as the same tread pattern and tyre must be on the same axle or I will lose my warrantee I opened a case with Mercedes Benz ,however after many calls and waiting I was told by Mercedes Benz there was nothing they could do and they closed the case. As things stand now unless Im willing to replace both tyres at my own expense I cannot drive the car until they and Pirelli get stock into the country which they cannot give me a ETA. as it is a new car recently launched by Mercedes Benz I would have expected them to keep spares, unfortunately for me this is not the case and I have too suffer the consequences as a result. My personal feeling on the matter is one of total disgust for Mercedes and as this car is my 5th Mercedes it will certainly be my last. Anybody wanting to buy a new A series please beware of this problem I experienced.
