Withdrawing funds in UAE

Hi
I am from Dubai UAE, I want to know the procedure of withdrawing payment in Dubai.
I read somewhere that I can use my master card on any ATM machine supporting master cards.
I went and used my card, after putting pin, and go to check my balance, the machine promoted with a screen saying

DYNAMIC CURRENCY CONVERTER
Amount in AED= 0.00AED
EXCHANGE RATE= 1GBP=4.475463 AED
AMOUNT WITHDRAWN IN YOUR CURRENCY= 0.00GBP

I want to know why is it showing GBP when I have USD in my payoneer account.
I found no option in the machine showing conversion of USD to AED

Please note I have USD less than 50.
Which can not be withdrawn directly to my local bank as it needs to be more than 50 USD.
There is also no way to top up payoneer account, else I would have top it up and maintained the balance to 50 USD to withdraw it directly to my local bank.

I lost 1 dollar each time time using ATM machine with a failed try of withdrawing money.
Also losing 4 USD every month for maintaining the balance.

Kindly help me what to do
Thanks in advance :smile:
