Vodacom is letting me down

Even though I have been using Vodacom for some time and the customer service agents are generally quite friendly and helpful. I can't help but feel that they are letting me down since about February 2023. I have specific questions regarding data specials and the disappearance of my data and all I get is the "Company Line". "It must ne your phone" or " the system does that automatically". Just once I would actually like to speak tl someone that can make an ACTUAL difference and help me out.
