last week I attempted to draw 300 quid from a Barclays ATM, it short changed me by 250 quid. As I bank with RBS I had to go to my local branch and complete a claim form in order to get it back. I also told them i wanted interest on the retained cash! Tonight I checked my online account and find that there is 300 quid back in my account, giving me a credit of 50 quid. Do I come clean and enquire if there has been an error or do I just keep stum? - I am for the latter just for the inconvenience suffered.
