Bank offers adjusted payment amounts and then refuses to take ownership of adverse impact.

I was offered an adjusted oayment relief on my monthly payment on a loan as a result of covid impacting my finances amongst other things. At the time my loan was up to day with payments. A consultant called me and offered the adjustment to which I inquired (calls are recorded as was emphasised by the consultant) if the adjustment would mean my account would go into arreas. The consultant informed me that it would not go into arreas and would not reflect negatively on my credit and rating. However, I then recieved a call at the end of June to inform me my account was in arreas with the amount that had been adjusted - I was paying 50% of my installment. My query is, once I informed the bank of how I had ended up paying the amount they said it was explained to me because I should have been aware that they dont alter the installment. I am highly confused as to how their briefing within their organisation to approach customers with adverse illinformed advise went. I am 100% certain that I emphasised I would not take up the agreement if it would accumulate as arrears. I have tried to call the branch without success.I have chatted with a consultant who said I must make the payments immediately. There is no responsibility being taken by African Bank as to their consultant who misinformed me as their client.
