Help recovering ltc that I sent to btc wallet

I sent ltc from my binance account to my nicehash btc wallet, can anyone help me recover them. Neither binance who says the transaction was completed so they have nothing to do with it and nicehash who says there btc wallet does not support ltc so there’s nothing they can do.

well, there is not much anyone can do for you, the wallets are in control of those companies, only they can help you out.
