Disgusting service, trashed my bicycle

I bought a Mongoose Mountain Bike from Sportsmans Warehouse. It had some problems with the bike so they offered to have it repaired at Hattons Cycles at Buxtons Center, Glenwood. I sent the bike in for repairs and they did not fix it properly. I had to send it back and they still did not fix it properly. THey have also stripped the bolts for the braking system. My bike is completely messed up because of them and when I phoned I got told \I don't give a f...ck:. I am disgusted at the service and quality of workmanship. "
