Came in for initial consultation was charged they never responded back except with bill

I called this office to see if Mr. Henningsgaard could handle a real estate transaction. His receptionist said I'd need to meet with him to find out. The meeting happened in about fifteen minutes where he said he'd look into if he could handle the contract. Then he disappeared. Never to be heard from again except for the $450 bill he sends me each month. On the bill, it says he wrote a contract. He never did.
