Oh that's a very good point though. Ebay support is great for refunds but absolutely useless w.r.t any account specific problem. I couldn't buy anything for 2 years a while ago and they would never explain why.

Turns out my old PayPal account had a minor issue, and that meant I couldn't use ebay even if I didn't even have my PayPal account linked to ebay anymore and I was using a new credit card. I had to figure that out by myself, ebay was completely useless and unhelpful.
