Bad service

I had 3 accounts with Nimble from African bank, got settlement offers and paid the requested amounts through another bank. Now the one account still shows an outstanding balance, this is how they make people pay more amounts as if it's a new debt. This is ******ion at it's best, today I called in and spoke to a guy named Kyle and he tells me that on his system it still shows a balance of R29k, while on WhatsApp it shows a balance of almost 2k.
