Bad service

I asked CWC to replace my sons MTB tyre with a major service. Waited 2 weeks for his MTB, only to be told that they could not get a 27.5inc tyre. Strange! I walk straight into a next cycle shop and bought one. Also when we arrived home, one of the gears was not working properly. I would expect this to be included in the service which costed me more than R1300. Maybe a good example of bigger is not always better. Not sure if I will make use of them again.
