Bad network, rude staff and disappearing airtime

My issues are long standing and I am sick and tired of Vodacom. My initial issue was the fact that I have the worst possible signal and data network in my area. I logged my query on Twitter (25-01-18). After complaining that I have still not gotten any feedback (27-02-18) I kept getting calls regarding a so-called "investigation". I get a call from an agent called Dylan. In a nutshell, Dylan decided it fit to tell me (a loyal customer of 18 years) that if i dont like the fact that they have no solution, I should change networks. He was rude, arrogant, raised his voice to me and completely disregarded the fact that I am a client - even going as far as attacking me and my place of employment. Barely even acknowledging the fact that I mentioned a secondary issue in which I am unable to load more than R10 airtime at a time, without it suddenly disappearing. I expressed my issues on Twitter (28-02-18) and promised to get a call back. Its 2 months later (24-04-18) and I have still not heard a word! Still ****py network, and I am STILL not able to load more than R10 airtime. If needed, I have the date and time of the call. I need a resolution and an apology and I refuse to wait another 2 months to get help.
