I sold an item on Ebay and the purchaser made the payment but did not pay for the P&P and he is in Belgium. I sent him a message requesting the p&p and he asked for my bank details, I gave him the sort code and account no. Now he says the bank in Belgium need my name and address too. Is this safe to give out? Does it sound a bit dodgy - he has paid over £250.00 for the item I sold!
