What is the name of the debit card that you use, are there any fees with it? Just curious.
For me, I prefer to play on Merge (Hero Poker) first, Titan poker
You could try Ukash, Paysafecard, Prepaid Visa/Mastercard to deposit on Merge if the debit option doesn't work. Or you could try to make an account on Neteller (or other similar service), then load some money into that account with your debit card, then make a poker deposit using your Neteller (or other) account. Kind of a workaround.
