I am very suspicious of Ebay now, after an horrendous lost/returned mail episode.
A firm sent me a non-ebay paypal invoice. I duly paid, noting all my details were correct. There was no browser auto-fill going on.
A week or so later, no item. Contacted the firm who said item sent over a week ago......to a click and collect outlet!! After much analyses and proving points on both sides, I headed to the outlet, only to find that they had rejected the item due to no Ebay collection code.
Contacted paypal. It took a week to sort but it transpired - and this came from a UK paypal rep's mouth - that ebay had somehow managed to change my preferred address to a non-paypal-verified address. Even when I went into my Ebay and paypal accounts, only my home address came up. The rep said he had flagged numerous occasions of this happening and it's not been acted upon.
Slightly off topic but note this as another Ebay red flag.
