Description of Work: Talked with them by phone. It was during a very cold spell in winter. they were very busy and could not come when I wanted. I thought I had forfeited the money. When I spoke with your rep this summer she told me to submit this form and get a refund. I appreciated her informing me of that. It has been so long. I don't really recall the date.
