Hi I have just sold an item but the buyer has messaged me a few times, first time to tell me he may have put the wrong details in to Paypal so would I check my account, no money, then we've gone back and forth stil no funds. He is now saying that the funds have gone through but are unclaimed on my side. There is nothing in my account just checked again this morning. What should I do? The really annoying thing is I sold this item before but the buyer didn't pay, arrgh!
