Of course this is a gear forum but I am looking to different places for general information and experience with this. My father is in his mid eighties and after a stroke has memory problems. He is hit with solicitors through his mail, at his front door and on the television stations commonly accessed by the elderly like himself. He doesn't answer his phone, good and bad. Some salesman got him to sign a contract to have solar put in. What does an 80 year old man need with solar? He cannot even figure out the correct date to write out a check let alone make a sound decision to have this work done. It would be blatantly obvious to everyone that he was not up to the task. This company took advantage of him. I just learned of it today. I have power of attorney and contacted to company instructing them to stop. I don't know what they have done yet. I will be going by there Friday and taking pictures. They told my brother in law they plan to bill my father and hold him to the contract. I will probably have to prove mental incapacity in court. At this point I don't know. He has cancer and doesn't want treatment so his health is not going to last. Any experiences to share or recommendations?
