We hired Kollmann Electric to move a generator. To start, they dug two pipes out of the ground and didnt backfill the trench. They also did not patch any of the holes in our foundation from where they pulled pipes out of the side of the house. We were left with large holes in the foundation of our house that they did not caulk shut. They also did not use hole closures in the generator. Most importantly, our transfer switch was working perfectly until Kollmann came and rewired it and fried our coil. Now they refuse to pay for something that they broke. They billed us and are now expecting us to pay for an incomplete job and left us with an nonworking unit. Their employees were also playing pool on our pool table while they should've been working. The owner Jeremy, is refusing to take responsibility for any of the mistakes made by his company or damage to our property.
