It sure if I'm in the correct spot with this one so please feel free to move as appropriate moderators. I got a gift of a perfect incentive card value of €50. They are prepaid MasterCard for anyone who doesn't know them, basically the same as a One 4 All card. Out Thursday before Christmas in Blanch centre and in quick succession I spent €24 in a small shop, then €17 in Debenhams. So with €9 left on it, I went to Reasons and the bill was just shy of €15 but I forgot to tell the shop assistant to only run €9 through the card........ And guess what, the whole lot cleared. So I'm now about €6 overdrawn on it. That evening I registered on their site and registered the card to my account in order to double check the balance. I figured I must have been given more than the advertised €50 but that want the case. The €17 transaction from Debenhams wasn't showing up and it told me I had €11.02 available to spend. Hmmmm, just maybe I used a different card for the €17! Just happened to be in Debenhams the next morning and bought something for €11 no problem and then checked the balance on my phone and the €11 had gone straight through. Christmas Eve the €17 went through.... Anyone ever experienced anything like this before? I have another few of these cards but am reluctant to register them on my account in case they take the money off one of them. Can they come after me for the balance? Who's error was it? The shop or perfect card or the merchant?
