No internet connection

I had installation for fiber on the 18th Feb and chose Afirhost as my ISP. They have no intention on having the issue fixed as they have been giving me the run around for almost a week. I communicate to them via whatsapp and all they do is apologize. They keep saying they looking into the matter and its being fixed. The agents i chat to have no soft skills and provides incorrect information. One agent told me that she does not have the power to escalate a complaint. She also said that she doesn't have the power to help me escalate the fact that my line was not active. I asked if i can change ISP's and they said that its to late. I threatened to expose them on social media and i was told "Okay, they'll give you feedback directly, thank you for your feedback." This is not customer service. They did not try contacting me directly on my number to advise me what the issue is. They keep telling me if the issue is not resolved i need to whatsapp them so they can update my ticket, but assure me that it will be fixed by then. While doing chats i asked the agent if they cannot call Vuma and demand feedback or call them frequently for an update and keep me updated, i received this response: "I only do chats hence I followed up on the tickets". This type of customer service disgusts me.
