On Friday, January 3, 2020, I had a new system installed in my home. I am paying $8,000++. Today, January 31, 2020, a repairman came to inspect the system. He indicated to me that a bulb had to be replaced. I questioned that. A new system has been installed. The repairman indicated that they put the old blub in from my all system. I was under the impression that I was getting a new system. Why was an old bulb put into the system? Today, I paid $110 for a new blub. I did not agree/did not sign the acknowledgement.
