tiptopbikes T/A bikes2ultd are a con dont buy from them

I PAID 620 FOR A QUAD BIKE IN FEBRUARY 2006 FROM THIS EBAY MEMBER. I AM STILL WAITING. THEY CONTINUALLY PROMISE DELIVERY OF THE QUAD BUT FAIL TO DELIVER IT. I HAVE DISCOVERED THAT THEY HAD BALIFFS PUT ON TO THEM FOR FAILURE TO PAY THERE RENTED UNIT IN ESSEX. THEY HAVE SINCE DISAPPEARED . HOWEVER THEY ARE NOW CLAIMING TO BE A REGISTERED LTD COMPANY TRADING AS BIKES2ULTD. I WILL BE CONTACTING TRADING STANDARDS WHO SHOULD BE ABLE TO TRACE THEM THROUGH COMPANIES HOUSE. EBAY ARE AT FAULT HERE AND SHOULD NOT BE ALLOWING THIS MOB TO TRADE WHEN THEY KNOW THEY ARE RIPPING PEOPLE OFF. EBAY HAVE NOT BEEN HELPFUL IN ANY WAY WITH REGARDS THIS. DONT BUY FROM TIPTOPBIKES OR BIKES2U, YOU WILL BE RIPPED OFF.
