Disgusting and unbecoming conduct by a Vodacom cancellation agent

I called Vodacom cancellations today(9 June) to request them to place a 30 days notice period for my contract that is ending on 08 July 2023. I was assisted by Nomncebo Zuma but that call became a serious nightmare. Instead of doing what I wanted her to do, she spent an unpleasant 27 minutes trying to sell me deals that I repeatedly said I'm not interested in. She made me feel as if I am forced to take another contract with Vodacom. After spending 27 minutes against my will, Vodacom has still not sent me a notification for the 30 days notice. Based on the level of service on this call I don't think I'll ever in my right mind do any other business with Vodacom.
