Hello. My grandson who lives across the street convinced me to get an inground pool. Fast forward to we hired a guy/friend who worked for an installer for 7 years and now works in plumbing but does pool opening, closing, liner replacement, above ground install etc on the side. He said he could install our pool. He ordered the pool and it was delayed alot. After 8+ weeks he said it will be delivered in a week so the hole was dug. The pool did not come for 6 weeks. It arrived Dec 14, 2020. Since then (today is Jan 27, 2021) he has put up about 6 panels. The sides have caved in, I do not think the shelf wall is high enough because the panels are about level to the grass, the deep end is way deeper and not at all the correct shape. The very scary part is my fence is very close to being in the next cave in. We are having a talk to see what his plans are, is he at a loss of how to fix the cave ins, what is the hold up. I feel we have just lost 20 thousand dollars because he doesn't know what to do. Is this salvageable? I have read and watched video about how to install so when we talk I have an understanding of what needs to happen. Anyone have advice what to do?
