Zap functionality bugged, funds stuckl

I tried to zap a fairly large amount of USDC for YLA in the V2 frontend hosted at the limo domain.
The deposit went through, 24 hours passed but, the zap did not distribute any YLA.

I also cannot use the “Release deposited USDC > Withdraw” functionality as it errors out with:
“execution reverted: SafeMath subtraction overflow”

At this point I don’t even want YLA anymore, I want my USDC back.
My USDC has been stuck in the zap contract for nearly two weeks. I contacted your support 8 days ago but still no word on getting my money out. Could someone please, kindly help me here?
