Not responding, and being vague

I ordered fiber in the beginning of November 2017. Afrihost did everything I would expect and Openserve came to install my fiber. There was a problem with our connection point (it worked, but needed some sort of update for standards). Telkom came to sort it out, and then Openserve came to install, but left without explanation. They said they'd be back in a few days, but never arrived. I have logged support tickets with Afrihost, and eventually they told me to contact Openserve myself. After a month of trying, I got hold of Openserve who told me the ISP needs to contact them. After that, I logged another support ticket, received a response that Afrihost would follow up, but I received no further information. I logged another ticket (every other one gets closed without being resolved), and I received a short and vague response to say that Openserve will install my fiber in March. Questions I ask are unanswered. I really didn't expect this.

I have been without internet for almost two months, and it is causing a loss of income.
