Misleading and false advertising

I have a home internet package with Vodacom and honestly "I AM FED UP WITH YOUR SERVICE". Since August I have been complaining about the buffering and your technical team feels a blue flying ****** to get back to me. I want this problem solved ASAP. UNDERSTAND THIS " I AM PAYING FOR A SERVICE WHICH YOU HAVE TO DELIVER, MY contract does not state" Home wifi with buffering. MY PAYMENT DOES NOT BUFFER TO YOUR ACCOUNT AS YOUR HOME WIFI BUFFER. Your slogan SAYS"GET THE Best.......... super fast and reliable LTE, Fibre or 5G. THAT'S FALSE AND MISLEADING ADVERTI*****T.
