"fee Maybank is not allowed to keep as it is a refund"
I don't find anything on maybank2u.com.sg that says Maybank will refund the fee in refund case.
Generally it is not the case http://www.nbnz.co.nz/personal/documents/visadebittermsandconditions.pdf#page=17
"In the case of refunds, the currency conversion charge applied to the original debit transaction is not refunded."
