Happened to me as well, ScotiaBank Cabarete denies transaction on my foreign credit card, my foreign debit cards are OK and without any ATM fee. Tried my foreign credit card 3 times and my bank cancelled the card as wellBanco HD Leon. Their message keeps telling me that my bank has declined the transaction. My bank says no, it was not presented to them. It could be a software error or it could be a result of me challenging (and losing) when they charged me for the $50 that I didn't get. I don't know. I have to ATM cards and both work fine with the other banks. So I'm not pushing it.
Had to make a call to activate the card. Hmm....Never repeated that again but checked once that the card is still denied.
The card are of course fine to use other places to pay for goods.
