Why Am I Unable to Refund My Customer?
There may come a time when you would like to refund your customer, but you're receiving an error message when attempting to do so!
This is likely due to the fact that your Available Balance does not have enough funds in order to process a transaction. By refunding your customer, your account would end up in a negative balance.
The only way to remedy this would be to wait until you have enough funds to refund, or by purchasing the product yourself, which would add these funds back to your account.
