A customer stopped payment on the final check after he said he loved my work, shook my hand and paid me. I deposited the check and 3 days later find it was stopped.....What do I do

Customer was very intoxicated most of the job. On the second day on the job I went to lunch and he called me very intoxicated, said I was fired, and proceeded to belittle me. I didn't know from day to day what the environment was going to be like. The last day I finished up the job. I told him a 2 ft. piece of bullnose I installed got wet and darkened up. If it didn't lighten up after it dried I would replace it. He said ok and paid me the check . I went right to my bank and deposited it. The customer called and left a message about the piece of bullnose that I could not understand because he sounded very intoxicated. I figured he would sober up and remember our conversation. That was the last I heard until I found out he stopped payment
