To see the description on the ebay phone app you have to click on the description tab to expand it. Not your fault if he didnt do it or if he indeed had a fault. You put a correct a description and if he chose to buy without reading (for whatever reason) then its not your problem. Whether he had a problem with the app display or not he still chose to hit the button. £6 is more than enough for rim tape which is the only thing you didnt cover. Let it go to ebays judgement.
i can kind of understand if he didnt see the descrition on his phone
but he quotes i m not entirely to blame (my description is spot on not my fault what so ever if he didnt read the description)
an also he reckons the bike shop quoted him over a fiver for the 4 nipples an £35 to true the wheel how much is it these days around £9 if i remeber correct?
it seems he wants to get the money back an have the wheel for nothing
i m not refunding him as i cant be sure i will get the wheel back
