I would like to raise a complaint firstly about the amount of time you have to wait to speak to Halfords customer services, which you should have a ring back service if you cannot take phone calls. Then after visiting your Congleton store last Monday and being advised about a hybrid bike by the manager, I purchased the Carrera Subway bike with the service package and some accessories totalling £350. I was told that I would get a phone call on Wednesday/Thursday to collect the bike, which never happened apparently the phone system was not working correctly, but the Manager never thought of using his mobile phone to inform customers. Then I called into the store on Sunday after being away for the weekend to find that my bike was ready after the PDI check, so I took it home. When I tried to ride the bike the chain was jumping off the crank which I found very dangerous, it was very lucky that I was not on a main road, which could have been more serious. I have just spent 2 hours this morning with Craig who has changed the chain and done numerous adjustments to the gears which finally have resulted in the bike changing gear with out the chain coming off. Also while I was there a lady came in with her rear tyre hanging off after picking her bike up this weekend. Craig is waiting for the third incident to arrive shorlty. The PDI was not carried out correctly and I have little faith with the service plan, I have paid for being carried out properly going forward. This was not a cheap or expensive purchase for a bike, but I feel that Halfords need to address the seriousness as this could lead to someone being injured.
