Alexander Forbes lack of communication

Alex Forbes administer my Nedbank pension fund which should be paid into my banking account on the 20th of each month, however my account was not credited on the 20th. I accept the fact that this could be a micro soft issue however the problem was Known on Friday the 19th. You cannot contact them over a weekend even the designated consultant is not available. There has been no communication from them and obviously I have had debit orders go through my account
