Recently purchased a Carerra bike for our son's birthday, Halfords set it up, took 4 hrs to build it, as "the bits in the box didn't fit together". After a few weeks whilst my son was riding the bike the back wheel came off, he was lucky that he wasn't injured. Since found out on Twitter this same thing has happened to another two families in the UK in the past two months. Store manager was very rude and blamed my son. Advised they could repair "the bike (that) was too dangerous to use" - Manager's words, but repair only at our cost. Not ok Halfords, after paying £300 for a bike weeks before. When I replied I will need to report this to Trading Standards as I don't want any other child to be hurt with their bike wheels coming off, the manager, said, "Trading Standards will do nothing". I had no idea that Halfords treated their customers with such disdain.
