Request for my refund

I tried to draw R240.00 ,from capitec,atm did not dispense the cash,but it was deducted from my account. It happened on the 16th August 2017 around 14h41. This is the first time i experience this . I immediately entered inside the branch to report the isssue they promised to get to me within 2 working days....i believe Capitec will refund my money back into my account.
