Unfortunately we are not eBay but other buyers and sellers and members. Whilst there are community managers that look over threads during the week they are unable to unfortunately help you in your request. My only suggestion is to request a call back via the CS link I will post below. Its always best to try early morning as you may get Dublin. However eBay usually stick by their word, so if you had a ban from 10 years ago or so, it is unlikely they will lift it now - so don't hold your hopes up.
