I was converting my BTC into another currency using ChangeNOW. I sent BTC to the address provided, but it took too long. I increased the fee, and the transaction went through only for the other party to not receive the BTC into the address they provided. I've sent screenshots to their team, but they claim they have not received any funds to their BTC address, even though the transaction was confirmed. Additionally, their response was:

"Your exchange has failed as the initial deposit was pruned out of the mempool.

No deposit was detected after that."

Is there anything I can do to recover these funds?
