Ans: Please do not worry. This happens due to your bank’s back end server error which usually happens during high traffic peak hours, when a card transaction shows a try again or declined message the first time the card is swiped and a second swipe is needed to complete the transaction. The ‘extra’ transaction is usually reverted back to your account by your bank itself within 48 to 72 hours. Please contact your bank to inform them in case you face such a problem. Please do inform us as well, so that in case, in our daily settlement report if we do see an ‘extra’ transaction we can meet your problem half way and inform our bank immediately. So far, we have never received any transaction twice in our account; therefore it is best if you checked with your bank first in case of such an event.
