Sold me a car with damaged spare wheel

I bought a car from AutoExtreme last month, before buying it i spotted that it had for different brand tires. When i asked them to change them they first refused and later changed them at half my cost . Then 2 days after buying the car i saw that the rim of the spare wheel was damaged. The tires was flat even! i called Henri Dique for assiatnce and he gave us the run around saying he will come back to us. Two weeks down the line we are trying to call him with no LUCK. AutoExtreme has a bad customer service and i wont reccomend anyone to buy their cars as they are only looking for a sale and cannot account for anything thereafter! Im disgusted by this
