Poor service with Afrihost and Openserve

I moved to Afrihost after having difficulties with web Africa. I started on the 1st of October with Afrihost with a migration of my line, all went well till the 13th of October where my line was cut off. I phoned Afrihost and was told the problem would be solved in 24 to 48 hours, it is the 21st of October today where this past week I've gotten the run around, I was told that Openserve needs to fix the line and yet still no connection. I work from home so i need that line I've had to buy mobile data resulting unexpected expenses to do my work. And they have now sent me a invoice to pay for the next month. they way this is going i won't be using their service for much longer if i only get 2 weeks of Wi-Fi
