I paid a civil engineer a retainer fee of $1400.00 to survey a property I'd like to build a home on. He initially postponed the start date twice. I shuffled my schedule to meet him on the third date but since I had other commitments in the afternoon and could not wait for him, left the check of $1400.00 as a retainer at the property. He came later that afternoon (Friday) and performed about 10 minutes of work, went straight to the bank and deposited the check. We spoke briefly as I had an odd feeling. He assured me that he'd be back on Monday, the latest on Tuesday. He never showed up and does not return calls. What is my legal recourse? Thank you very much.
