Common Examples:

1. Linda went grocery shopping and swiped her card to make the purchase. She didn’t realize and hit the option “yes” to the question if the amount was correct. Later she tallies her bill and cross checks the amount to find out that ten more dollars have been added to the bill. She therefore, goes ahead and disputes the charge with the help of her bank under the Reason Code 4831: Transaction Amount Differs
2. George went to a restaurant with a few friends. Few days later, when he checked his account, he finds out that he has been charged more than he was supposed to pay after the split as he also has the receipt with him. He calls at the restaurant and requests them to look into it. The restaurant claims that they have charged the right amount but, George is certain that there is a mistake so he disputes the amount under the Reason Code 4831: Transaction Amount Differs.
