False advertising on low balance notifications

I was informed today that despite immediately rectifying my account on an overdrawn notification, rectification is not enough and I had to call in, because your system is manual. So the 30hours time in which as advertised is false. As this was done. 'Instead it should state notify us first' before or when you rectify the account. Despite me rectifying the account the debit order was returned 24hours after the account was rectified or 6 hours after it first went and 30 hours after it was returned. DESPITE the account by then was well within time frames in a ostitive balance.
