from DO’s FAQ section, what i can see regarding your issue is

Q. Can I transfer credits from one account to another?
A. No - credits cannot be transferred between accounts.

but you can still contact support to take a chance.

@pacosta

If it’s promotional credit, I’m pretty sure that’d be non-transferable, though if it’s credit resulting from a deposit, they may allow it.

You would need to submit a support ticket through the control panel to see if this would be permitted though. By default, there’s not a way to do this on the user end.
