Tweeter subcontracted with Elwin for in-home repair for our 50 inch tV that is still under warranty. Elwin left a message on our answering machine that said they would send a service tech between "2 and 6" tomorrow and that we should call before 8:30 if this was not convenient. I decided to take a 1/2 day off work to meet them at the house. By 4:45 they never showed. I called and they said they were not coming. That our service call was canceled because we did not call. We called Elwin to try to resolve the problem and they were rude and not accommodating.
