There are loads of advice articles about eBay shopping so I looked some info up for you Diamond Diva I don't know how it happened, but I've just bought a ring.
I've had a couple of orders cancelled over the years and I think the refund has been fairly quick. I seem to recall having the same messages as you last time and not quite knowing what was happening but it all sorted itself out eventually.
I finally got the message from ebay saying the order has been cancelled, the seller told me that himself 7 days ago!
The refund should be with me in the next four days so we'll see. I've bought the same item from another seller which arrived within 3 days, obviously I've had to pay for that too with a refund still out standing it's so annoying, hey ho these things happen
People who are wrong are just as sure they're right as people who are right, the only difference is they're wrong
