Extremely disappointed with capitec after being with them for over a decade

When the Covid-19 pandemic started in March last year I was offered 3 months payment relief from Capitec Bank. And then boom my loan agreement was now extended by 13 more months that was not explained to me. Meaning I have to pay extra R 38 233.Yet my 3 months break was only R8 823.I called all capitec departments that should assist and I was never assisted at all. All they could tell me was that they can increase my installment instead. I find this very strange as I only took out payment break that was offered.. Now it is like I took an extra loan at Capitec. Till today after a year my issue remains unchanged
