HOW'S THAT POSSIBLE?

I made a R1100.00 ATM deposit into my Standard Bank on 31/07/2015 at 19:08. The money hasn't reflected yet in my account. I lodged a complaint and they said it would take up to 7 days. I know the 7th day will only be on the 7th of August 2015 but now this is too much inconvenient. My bills haven't been paid off. When I phone Standard Bank no one knows about the progress of my complaint. This is sooo unfair. I was not at fault! I'd like the bank to please look at this matter. My bills life is currently a mess at this stage because of this. I don't want a bad credit record. <br> <br> Please assist, immediately!
