Recovering ETH sent on BASE network

Any mechanism to recover ETH sent from (NDAX) using BASE network to (Shakepay) ERC20 only?

Recipient Address is a Hot wallet hosted by fireblocks i believe. Any direction would be appreciated.

TxID:

0xc1a957b6b25da47f527430e930e850441431a60b173b6cc3c1acded43d889ad9

Seems I have to connect a wallet to try and access that.

I tried to email support but was told I have to access it through the user support centre, but that introduced the hurdle of a corporate account.

Any idea how I can attempt to get in direct contact with them? Happy to pay associated fees to be honest.
