Well I've been a right idiot. Changed my email address for ebay and paypal ages ago. Listed a few things this week, payment by paypal and with bin on them. Sold a pushchair on bin for £100 last night sometime. Anyway, I never checked when I did the listing, instead of using my new email addy for paypal it's used my old one. The buyer has already paid via paypal, and I can't claim the money. I have emailed the buyer and ask if they mind cancelling the payment, and i'll give them the right email address to use. What a mess, they are going to think I am conning them aren't they? I probably would. Any advice please?
