Query: poor quality

The volume switch comes loose and freely spins I called company and they had me place it back in it's slot, easy to do but this has continually happened, at least 4 times in 3 weeks. I have made 3 calls to company and they promise to send me a fix, a small screw to hold the switch in place has not arrived in 1 week am going to call again and complain.
