Worst service since January 2020

Good day, Can someone please help me with the contacts of a senior person working for Vodacom? I've had queries since January and they never respond to me. They'll just say they're investigating then boom, ghost on me and tell me to call accounts. I've been sending the emails, DMs on twitter but with no luck. They know they deleted my number but will tell me to call customer service, which requires the same numbers which doesn't exist. Vodacom is the worst when it comes to service. They're not even interested in solving the matter. After taking all those necessary steps with no assistance, can I ask for a senior person to contact from Vodacom?
