Wrong spare wheel

Very disappointed customer and I definitely won't recommend them. I bought a car with them last year, and they’ve been giving me problems since. I recently had a puncher and wanted to change my types all to find out that the spare wheel is a 15” and my tyres are 16”. It doesn’t sit well my car is imbalanced. I spoke to a guy named Clint on Sunday he’s been promising to get back to me till today no luck I’m driving with an imbalanced car. Don’t buy from there people
