Insulted by Absa Consultant

On June 2022 I made arrangements of paying R1900.00 extra for settling arrears on my Absa loan. I was under the impression that in August the arrears will be paid up. on 20 August 2022 when I inquired I realized that arrears were not paid up. On 03 September 2022 I phoned Absa collections department and asked to rearrange the amount I am paying towards the arrears, the Consultant who hadn't even Introduced her name to me said its not possible to rearrange the amount I am paying towards the arrears.I asked her how on earth ist not possible because I am the one who made those arrangements and I am the one who knows how much I afford, She said "I am insulting her and I don't have manners" I asked her that do you always insult clients? She said "just pay your arrears and stop complaining, your account was not supposed to be in arrears in the 1st place" I am very disappointed with how She spoke to me.
