I have a buyer who is being beyond abusive. They are and have been misusing the ebay system to cause as much carnage to us as possible. I have spoken to ebay support who have been absolutely no help, and even suggested that we continue selling to them despite the history of problems they're causing.

The inital cause of their frustatration is an international return that they forced open and was eventually closed in our favour because of the outright lies they were claiming as truths.

We blocked them and hoped that would be the end of it, they have since created approx 5 new accounts to bypass the blocks that we keep putting on their account, we have spoken to them and asked them to stop creating new accounts and to stop ordering from us but they continue anyway.

Each time they make a new account and place an order, we contact support who usually tell us to cancel the order, which we do. This is fine, but they just then leave scathing negative feedbacks. Despite ebay guidelines saying these reviews will be automatically removed because ebay instructed us to remove them, they're not alway removed - leaving us with this terrible reviews on our account.

The customer has recently placed an order with another account, and for some reason ebay support has told us to send the order to her, even though we warned she would make trouble some how.

The order was sent from UK to USA, and unsurprisingly she has opened a return request, falsely stating that the measurements are incorrect, which they aren't (everything was triple checked before sending to her because of these issues). She is now demanding we cover her return costs and reimburse her initial postage.

Ebay support have said we should accept the return and report the buyer, and they will then refund the cost of return postage, but ebay guidelines say this is capped at £3.50 (return postage will be about £20). And in the past we have used this reporting function but never actually received a refund, so doubt it will actually happen.

I'd really like to talk with someone that might actually be able to help me out in this situation. Would be greatly appreciated. At the moment it feels like this customer can get away with literally anything with no issues.
