Pathetic Accounts Handling

This complaint is on behalf of my wife. 1) I pay her account monthly by EFT. 2) I pay WELL in advance. Usually more than a week before due date. 3) I always pay MORE than what's actually due. Twice now (first in December) and now in July my payment wasn't allocated. Even though I pay in exactly the same way every single time. In December after dozens of phone calls and emails they "found" the payment and allocated it to my wife's account. HOWEVER my wife's credit record on ITC / Transunion shows "30 days late". In July, same story. I paid R400 on the 24 of June. R400 is more than double what was due and it was paid more than a week before due date. My wife gets countless phone calls, SMS's, legal letters demanding payment. And once again ITC / Transunion shows a late payment. Eventually after a MASSIVE struggle, they "found" the payment. Yet we are STILL getting phone calls (latest one this morning) demanding payment and warning of legal action. My requests are: 1) FIX the ITC records for December and July. 2) Send us a settlement amount so that I can settle and close this account. This is by far the worst customer "service" if you can even call it that I've ever experienced. It's shocking - insulting and basically sums up what's wrong with this country as a whole. Pathetic.
