Where's the money gone??

On the morning of Friday 28th February, my usual automatic payment was deducted from my current account to pay off my monthly Credit Card account. 4 days later, this money has still not been app**** by Nedbank to my credit card account, No logical explanation has been forthcoming, and no indication of when the problem will be resolved. Is it just my account, or have they done this to others this month end? The joke is that I am a long standing Private Bank client assigned a personal banker, and the best they can do is say "we are working on it"
