I bought an XR50 off ebay. At the close of auctyion, I immediately paypalled the deposit and sent an email asking the seller to contact me to arrange pickup. After not hearing from him in 24 hours, I got worried and cancelled the paypal payment before it was accepted and emailed the seller again to contact me. It's been 2 days now without hearing from him. What is the standard length of time I should wait before doing something else? Would ebay provide me with a phone # if he's not responding to emails? Are there any other options I may have?
