Loan term after relief

Capitec operates like ********, 2019 August l took a 80 month term loan with the installment of R2253.88 than 2020 covid hit us and like many companies ours also suffered, as per the bank's ad about the 3 month relief l requested for one. I had already paid 9 months on my loan, the relief was granted,than l few months back l went to the branch to find our the progress of my loan as l was back to paying the normal instalments after my relief break only to find out my loan had been added another 20 month so from the 71 month l had remaining l was now on 91 months,been trying to get assistance and unfortunately am being sent from piller to post only yesterday l was sent a supposed new contract with the 91 term loan which when l inquiry about it am told no assistance could be given to me since l asked for the relief via SMS. I feel ****** to a point where my trust l had for the bank is no more.l can not get any assistance and paying this will be unfair as l can not possibly pay this much.
