UNFAIR CONSUMER RIGHTS

I got a call from MBD agent regarding my debt that I should pay and I requested that she can do the debit order transaction as I wont be able to visit the bank. Then I requested her that she should send the full details of the account to make the payment arrangement on my whatsup as I was driving. She sent the information and demanded that I should pay R500 which I told her I won't be able to pay today as I don't have money then she threatened me that I should pay the R500 otherwise she will do the litigation and enforce garnish to my employee. I further requested her full details of my profile and her details so that i can lodge a formal behavior grievance to her company and refuse to give the information .We were communicating on Whatsaup and her name is Dineo Mosia
