Pathetic Service and completely unhelpful!!!

I made a payment to Vodacom Collections Agency (TS Legal), regarding my vodacom contract. The payment was related to settling my vodacom contact which i had about two years ago. I made the payment on Monday and sent them the proof of payment on Monday. I called them this morning to get a closure letter which I urgently need and have explained this to the consultant (SIMA) numerous of times. I then asked to speak to the manager (Yolandi) and explained and expressed the urgency of this letter. To date I'm running around in circles to get something as simple as a VODACOM CLOSURE CONFIRMATION LETTER!! If this is not resolved today i will take this matter to the Consumer Protection Counsil and the Ombuds for services not rendered.
