I had funds held up from Amer Express and called them. They said that a customer was disputing charges made in June 09. I then called contractor and he said the customer ran out of money and asked if we could take payments. I then talked to the homeowner and he said he overpaid the contractor but the contractor will pay us. I did not file a prelim because we were paid right away. Now the homeowner is saying he will not pay us and to go after the contractor. The contractor is saying something different..what are my rights?
