Complaint

I took my car Mazda CX3 2.0 for service to Eastern Cape motors East London on the 5th of September. I noticed that they have changed my spare wheel and the jack because the one they gave me has never been used before and the size is smaller. I have used my spare wheel three times and there is no way it can be this new. I went to them and told them about it, they didn't wanna give back my used spare wheel and said all the Mazda comes with that spare wheel. My spare wheel rim was all black and the one they gave me has a yellow rim and has never been used. The manager said I must give them proof of the tire I had, told them I didn't take photos because I didn't know this would happen, they refused to even check on their cameras. If this was a white person they would have jumped but because I'm black had accept their *****ed work. I will never ever trust them again and it was my second time buying a car from them but they are ******
