Excessive telephonic BANTER & HARASSMENT after making a Payment Arrangement before even defaulting!

I was treated like a ******** for not paying an amount less than R270 (as arranged) before I had even been paid! I told that operator that I mostly only pay on the very last day of the month, but for the past week I have been harassed with calls during work, after work,...up to 12+ times a day!! I eventually ignored the incessant calls but then decided to answer but every time they hung up. Tonight, after yet another 12+ call attempts during the day I finally answered (AFTER HOURS - 17;40), asking the operator not to hang up after which he claimed not to have hung up on several calls before, which is *******!!!! When I tried to explain to him that I had not been paid yet and that I would make the minuscule payment over the weekend he started yelling at me without giving a chance for me to even get out of his vice grip and a " screaming match ensued after which I just bowed out. . NO, NO, NO, NO, NO, NO, NO, NO etc. You do not treat a customer of nearly a quarter of a CENTURY this way over R260. It simply NEVER excusable, especially in such an arrogant and pedantic manner. SHAME on You TRUWORHTS with which I'm now Done!!!! NO more ABUSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I'll pay off my measly balance of R840 as arranged as explained above, CLOSE my account after more than 2 DECADES and then you can go straight to HELL for all I care!!! You are a Useless and Redundant Company who's days are numbered: Your prices are exorbitant, quality beyond questionable and your methods of recovering dept has NO structure, system, communication and decency and importance toward the customers who make payment arrangements with you. That is abominable!! : Easy to give Credit but relentless and Cruel in your approach to the very Customers who keeps your *****ED doors open. CLOSE FOREVER!!!! When I close my account on paying up my measly balance you can shove my handsome Credit limit up yours!!!!!

Good night and Good luc****!
