Owner didn't complete pool and ran of with money

We are at end of week 6 & since I accepted the quote in Oct & paid the dep, he & his men has worked on/off not even 10 days. First his mom died & he started a week later than planned & after hearing nothing from him for almost a week after paying the dep. He eventually started the work & then a friend died. He didn't pitch for another week making excuses & then promises of coming but never showing up, I have proof of all. Then according to him his main man's house burnt down & still he didn't pitch, although he promised to. Just can't believe that a business comes to a stand still if 1 of your guys didn't pitch for work but you started off with 5/6 guys working the first few days. At end of week three he said he won the lotto, R5.5mil to be exact & that he'll be fixing my pool for free as it'll be the last pool he'll ever fix as well as give my dep back the next week. So week 3 became 4, 4 became 5 & now it end of week 6. He didn't show up at any given time during that period & had excuses of why he's dragging with the pool. When he did eventually answer my message last week he said he'll do my pool for cheaper & will start Monday, but never showed or answered any of my messages
