Card Blocked - International Travel

I have a discovery gold credit card and travel internationally every year on holiday. Every year i notify Discovery of my intention to travel before i go, they are very helpful and professional. Last year i was in Hong Kong and when trying to draw cash at HSBC the ATM gave me the \incorrect pin\" prompt and blocked my card after 3 attempts. This year i was in Thailand and after 2 attempts of the same \"incorrect pin\" my card was blocked again. Never has this ever happened in SA as this is the same pin i have had for years now and, i was extra vigilant this time. I am 100% certain that my pin was entered correctly.<br> My card is still blocked and although it will only take a phone call to unblock it i am contemplating rather just going to ABSA and getting a card from them since they are my primary bank anyway. It may be easier to just close my Discovery card.... "
