Have you removed the rear wheel to check if the spacer is in between sprocket carrier and wheel , and all the cush drive rubbers are there , also has the rear spindle been torqued correctly ? just tightening it FT can cause probs, if they forgot to tighten the caliper there is no guarantee that everthing else is ok !!!!!! at the very least, drop the chain off the wheel and check that the wheel spins freely without any noises, sorry to be an alarmist, I've experienced some real knuckle draggers in the motor trade .
