ADSL

I am sitting with an ADSL problem since the beginning of January 2016. The original call was closed without the problem been solved. I had to log a new call with them, this was resolved on 16/02/2016 after plenty of mails and phone calls. Today I am back with the same problem. My internet connection have dropped so many time over the past hour that I have stopped counting. My 10mbps line is down to 5.18mbps. I want to know when Afrihost will fix my ADSL line so that it stays up for more than 2 days. I need to do standby work from home and is unable to do my work at all due to the line that keeps on dropping. Why am I paying for a service and then receive this level of ''expertise'' and service. In the past hour I am unable to send an email.
