BAD to NO internet on ADSL

I've been having connectivity issues for the past year, and nothing has been done about it. I work from home so need a good and stable internet connection. Im also on a premium package from mweb (Not that i get premium service). I've been phoning them about 3 - 4 times a month about my connection, and all they do is reset the port witch is a temporary fix but doesn't solve the problem. Now that i have moved my line doesn't even want to sync at the full speed. I've been phoning and requesting technicians to come out to fix the issue but nothing has been done about it. I'm getting really tired of struggling and want this matter resolved. Its been escalated about 2 weeks and haven't even received feedback.
