International Transfer Problems: No Feedback!!

I work abroad and my salary is paid into my SA account on a monthly basis. To govern this, ABSA has a valid SSI on file. The last payment made to me on 26 April unfortunately contained a typing error (incorrect initial) and ABSA withheld the release of the funds into my account, asking for an amendment letter. (I am not sure where the typing error was made, but there you have it... Also, I received no notification from ABSA that there was a problem: I had to start making inquiries on my own when the money didn't show in my account.) The amendment letter was delivered, together with a copy of the SSI, and I received a mail on 21 May saying that the funds will be released. 24 hours later still no money in my account, and no response to inquiries sent to the responsible department. I really don't know what else to do but to complain here! Any advice please? It is almost a full month since the payment was made: who has had the money all this time? I TRULY would appreciate feedback from ABSA. This is simply not acceptable any longer.
