Worst call center experience trying to sort out debit order!!

I have never been this frustrated dealing with call center consultants! GEMS is the absolute pits. My rating is less than 1 star. THEY made an error, out of nowhere, on a debit order and debited my account TWICE in one month - both amounts incorrect. Perhaps someone was attempting *****? I reversed the second debit order and the debit order subsequently got cancelled! Later that month I RESENT FICA documents to have the debit order reinstated and 3 months later this has still not been done. Imagine?!! The colleagues from both contributions and membership departments don’t seem to know what’s going on. How do you explain that?! Today I spoke to someone who said the FICA documents were not correct! These are the exact same documents that I sent in January which were sufficient then. Also, why has this not been communicated?! Is one supposed to smell that the required documents have suddenly changed? Not everyone is well-versed on the POPI Act and the implications thereof! I am honestly at my wits’ end with GEMS. The service is way below par. To say it’s poor would be a gross understatement! All I’m trying to do is to reinstate the debit order to get the account up to date. This should be the simplest thing to resolve.
