I paid over £1200 for two quad bikes from fun4bratz2play in August, I haven't received anything either and I know many others who are in the same position.  I have had no joy from ebay who must have had contact details for this fraudster because they wouldn't have been able to register otherwise.  I would go to the police but with only a PO Box number to go on it's difficult to see how they could be traced.  If anyone has any other details such as bank account details I will try and trace them.  For i nfo Bikes2U have their registered office at 191 High Road Chigwell - Pay them a visit!
