Then you unfortunately can't do anything about it.
It is completely up to them how and when to recover wrongly send coins.
Please not that this doesn't mean they are 'scam', 'untrustworthy' or similar.
Accessing the private keys to recover funds sent to an wrong address is a time-consuming and highly risky process.
Security-wise it definitely makes sense that this is not easily possible. Most employees have absolutely no access to the private keys.
Accessing the private keys outside of the fully automated process which handles withdrawals is bound to huge risks and it makes sense that they do not accept the risk for an amount which seems to be 'too low' for them.
