Usually the banks used to send the ATM cards stuck in their ATMs to the respectve banks within one wek time, so first check with your bank (who issued the ATM card)if it is returned to them, if not just apply for a new card that's the easiets way (The chances are less as you lost it at ARAB BANK ATM, because I had the same bad experience with arab bank ATM at Markhiya Petrol station and when I called them they said it will be returned to my bank, but it did not happen even after three weeks and I applied for a new card).
