Af Waterproofing

Joe had made a contract to make new outside weeping system with extwrior waterproofing aroutdoor the basement of my house. After two days of work, he stopped the work asking for another $3,000 downpayment. I paid on good faith that he will do the job timely. Two day later, he asked for extra fees of $3000 to be paid to him as additional downpayment. Though I agreed to pay him the money, he disappeared and not responding to any call or message!
