God! Name the shop ??
To behonest loads of bike shops are getting worse, they'd rather sell bikes as a whole than repair one.
My Son had a brand new BMX a few years ago and the rear spokes all came loose within 2 days, I told him to take the bike back and get the wheel sorted, being brand new I expected the wheel to be fully re-tightened up for free, but oh no the bike shop wanted £12 to do it!
I phoned them and gave them an ear bashing and they bluntly said ''We are a business and not a charity and don't do things for free sir''.... I told them this is ridiculous as the bike is only 2 days old, again they said ....''There will be a charge sir''.....So in anger I said.... ''Right I'm bringing the bike back and want a full refund of the £375 purchase price as the goods are defective and suitable for use''..... Silence on the other end for a good few seconds, then someone else spoke to me telling me to bring the wheel up and they'll tighten it up for free.
Never been back to that shop since.
