Credit Card Blocked

Yesterday I tried to buy a \old stock"Laptop on special of which only 2 were available using my card. The transaction was denied. I phoned the Platinum banker at the Alberton Branch to inquire what was going on. The response was that a certain number of cards were blocked due to high incidents of ***** over the holiday season.<br> <br> My problems are that I used the card about a week ago with no problems and I received no notification or explanation why my card was blocked"
