Contravention of the National Credit Act - AGAIN

I don't deny my account is in arrears but being currently white, female, disabled, over the age of 40 and unable to secure employment - I started doing freelance work which is slowly picking up but with the ******s, *****, armed ******ies and xenophobic incidents going on this country, the economy is very slow. I made a payment arrangement with AB and even when I don't have money I have always paid the arrangement amount. Today Sabello phones me at 16:26pm and insults me! To summarise: we don't accept your current payments and want more...I told him I don't have more...he says that's not good enough...I tell him I don't have family to rely on for help and he says then my responsibilites should be less and I should be able to pay AB more. I ask to speak to his manager...he refuses to put me through to his manager. He refuses to tell me his surname after I tell him I'm going to report him. Bottom line...AB I HAVE a payment arrangement already in place and have not defaulted once with the payment arrangement so why the harrassment? Why the arrogant and rude call center agent? I'm acting within the NCA...do I need to report you to the NCR..this is not the first time you're out of line!
