Buyer wants refund 11 days after receiving item and my account has been banned
So a bit of context i have/had an Ebay account and last week received a ban for exploitation of the refund policy. Of the 7 things i've order only 1 items has actually been accepted by me and 1 is yet to arrive. On the face of it it looks bad and i've accepted the fact i wont get the account back.
But the items being refunded weren't actually my fault: 2 items were never posted and the sales cancelled by the seller, 2 items were fakes sold against Ebay T&C and returned at the request of the seller, 1 item had a damaged label and was returned to the seller as it couldn't be delivered.
I've called CS and get the same response, my account is banned and i have no recourse through them, they've revoked their buyer protections.
But i've just had a message from a buyer i sold a watch to on my account (that they've had for 11 days) saying there is nothing wrong with the watch they've just changed their mind and they're now saying they want a refund, can i still process the refund and get the watch returned as i have no options for this and eBay are saying they'll refund the buyer automatically if i dont respond?
I've also been waiting for an item to arrive that's been in transit for 21 days, that was meant to have come from Leicester but is arriving from Dubai that i cant challenge and i'm guessing i'll need to charge back through my bank as it's bouncing around in the UPS system for a week. It was this case that got my account suspended i'm guessing the seller reported me after i challenge them about where the watches were coming from and the inconsistencies in their listing.
What has happened to eBay, and what can i do?
