Roofers Roofing

The skylight in my guest bedroom was leaking. On June 27, Wayde Wilson the roofer came to my house. He went up and checked the skylight He came back and informed me that the skylight was leaking because the nails in the shingles had popped up. He said that instead of nails, there should be screws. He said he would go to Home Depot and bring some supplies and that it would cost me $300. He also said I would be good for 6 months maybe as long as a year. He collected a check from me, cashed it very quickly. Four days later during the next rain, the skylight was leaking again and it had even spread to the kitchen below. When I informed him, he said he would be back in a few days. He never came back. When I asked him to return my money, he refused. I feel completely swindled.
