Peterman Brothers Heating, Cooling, Plumbing & Electrical review: Tried to charge me $1000 and never fixed anything

On April 1, I had an appointment scheduled for a clogged drain. When I called to cancel they suggested I get my electrical panel looked at. I agreed due to our electrical bills being over $100 higher than usual. Their salesman said it was being caused by electrical panel and it would need to be replaced. He also stressed how we were at risk of a house fire if it wasn't replaced immediately. We agreed to have it replaces but found out later that day, that it wasn't the electrical panel that needed to be replaced, but it was due to a repair that Aron from Peterman Brothers didn't do correctly on 12/27. We looked at our energy bill and realized the higher energy bill started right after his "repair". We found out he wired it incorrectly and connected our furnace to run of emergency heat. We also were told that there was no danger of fire as well. We immediately texted, called, sent a message through chat and sent an email canceling the order. The loan company canceled the loan, but now Peterman said they need to keep $250 from my deposit. There was no mention of this with signing up and they made no attempt to correct their error from December after finding out their guy didn't do his job the first time. This whole experience has been a nightmare and we just want our money back from these con men
