This seems to be normal now with the card provider. The customer rather than tge provider is always right. Seems to me the client read the report and decided not to proceed. This was the way to get the money back. Interesting that they want to sell on the report if it wasn’t good. I think this is typical of the way clients try to get rhe money back. It is very common with Amazon. The fact they don’t want to use your complaints process underpins this Having had problems with Amazon and PayPal I think it will be difficult to win. SORRY.
