Still waiting for feedback

I have a query that i would like to know what i should do and where can i go. Anyway i have been with Afihost for not even 6 months and i have had the worst encounters when it came to service delivery and have had the least customer satisifaction from them that i have ever experienced. Firstly i have been constantly on the phone with th company speaking to several consultants, whats app agents, managers and even the managers managers and still nothing has been done regarding my bill. I have informed them that from the beginning i have questioned regarding the 2months free service that was part of the deal when i signed up with them. For them now to tell me that i had to read terms and conditions and that is the reason why they needed to charge me. So my question to them was why have i been promised before sign up the two months free by one of their whats app consultants. Still awaiting that whats app chats that i have requested about two weeks ago already. Nevertheless i paid the amount so that my internet connection can remain on because i currently work from home and need the connection. The second thing Is that i have signed up for a 20mbps line and until today have never received that speed. I have brought thia also to their attention and since November 2019 nothing has been done and no feedback from Afrihost. Dispite the fact that i follow up for feedback they cannot give that to me. I then requested call recordings and tickets logged for this issue and its been two weeks now no feedback or reaponse from the relevant managers that i have requested this from. I have called for feedback several times and no one can give me a progress report on me query. Third thing was i have tried to communicate with Afrihost via social media and got some response via a comment that i have added to one of their posts. However by doing so one of the consultants posted my outstanding balance directly on the public social media page. What i did was screenshot that response and Immediately reported this to Afrihost sending them the screenshots of the incident. The feedback that i got was that it was a private message. Where it clearly states private tread on the screenshot. I then disputed that and still waiting for feedback. Can anyone please assist me and tell me what i should do because i cannot understand why such a company still has their doors open. And if this happened to me how many other people are they doing this too. Please help!
