I bought some boots that were smaller than described and worn when told brand new never worn. Seller de-registered as soon as the sale was complete and wouldn't respond to emails so I opened a paypal dispute for a refund. She has responded to that but says won't refund until she gets the boots. I am worried that if I do she won't refund me - has anyone gone through all this and knows what to do? I can't find anything clear on the paypal website.
