A common situation: someone buys item; eBay seller goes to Amazon and buys the item from a third party seller; Amazon seller sends item to eBay buyer as a gift.
What is the procedure for reporting the eBay seller? I realise that I will most likely be wasting my time - despite using Amazon as a dropshipper being forbidden in eBay's terms and conditions. EBay ignoring complaints against those breaking its own t&c's is not unheard of.
("However, listing an item on eBay and then purchasing the item from another retailer or marketplace that ships directly to your customer is not allowed on eBay." https://www.ebay.co.uk/help/selling/posting-items/setting-postage-options/drop-shipping?id=4176 ))
