right I sold the cheapo tyres off my m5 rep wheels as I will not skimp on tyres!

there was nothing wrong with them and I checked this before I sold them this was a on the 9th of october and now today the buyer is saying that they have sidewall damage and are unsafe etc
I have worked in the tyre trade for well over 10 years and been an mot tester for about the same and would NEVER sell anything that wasnt fit to be used

Sooooo how the fuck can I prove I have done nothing wrong as Paypal are holding £90 that was in my account

This is my ebay add
