Sorry to see this. I had purchased a half tub 2nd hand from another mudder a few years ago. IT had originated from LCH. IT was junk, completely useless. I sold to someone with some metal skills but even it exceeded what he could handle and I ended reimbursing him some funds to make it right.
Hopefully some character/integrity will make it right for you. That's a ton of coin.
