I collected the brand new bike from Harlow branch beginning September.After 300 miles in 2 weeks the 'nut' holding the front brake and mudguard to the front forks fell off without any warning and the front brake dropped onto the front wheel. Luckily I was going slowly at the time and managed to stop safely. I couldn't find the nut and thought it would be easy to get a replacement from you. I rang the Harlow branch and was told one would be posted to me shortly. After 7-10 days I rang again and was told again one would be sent shortly. after another 7-10 days I rang your head office and asked for the same thing and was told they would send one shortly. Nothing has arrived.
