Utter stupidity and obscurity in Nedbank Online Banking

Nedbank has some bizarre algorithms. I am a pensioner and I receive my pension on the last business day of every month. It usually reflects online as "Pending Credit". Why? Goodness knows, the bank already has the money from the pension fund to pass on to me. Some months ago I received my pension plus a payment from another institution that I was expecting, both on the same day. However, both appeared as a single combined "Pending Credit" and the amount was not what I was expecting. It was a Friday and the separate discrete amounts were only shown as two amounts in my account on the Saturday. Only then could I pick up where the discreancy was, but I could not do anything about it until the following Monday!!! Many complaints resulted in Nedbank reflecting two "pending credits" when this happened again. But yesterday I again received my pension and a payment from another institution on the last business day of February. They have again reflected as a single globular "Pending Credit". I fail to understand the logic behind this stupidity on the side of the bank. They receive two payments to pass to me that have to reflect separately in their books. It must cost them money, data time, and the services of an algorithm and may be a human geek who is paid a salary to merge the two payments into one to reflect on my account as a single "Pending Credit". What on earth for??? It causes the customer aggravation and it costs them money. Why the H*ll Do They Do it?
