TV Workbench

My elderly mother recently called this service for a repair. She told me that the service repairman sat on her bed for a few minutes looked at the tv he told told her ther was nothing he could do to fix her tv. She was unable to turn it on with the remote. He said he was in a hurry to go get his wife a birthday present and that she owed him 90 dollars for the visit. She paid him and he left. When she told me about this we got someone else who just turned it on with the touch screen button which my mother was not aware of, and it turned on immediately. My concern with workbench tv is that I feel they did not do enough to diagnose the problem. And i feel that they saw and elderly woman alone with mild dementia who is very trusting, who could be easily be taken advantage of. When I called workbench to discuss the situation, the person who answered the phone had a slightly aggressive tone through the conversation which prompted me to hang up. He immediately called me back and told me that he fixed the tv which was not true. I informed this person that I would be reviewing his service on Unilocal.I would advise anyone to not use this service or use it with caution
