Cannot cancel account

I have been trying to cancel my account since 20 July 2015. I want to cancel my account for the end of July as I have had really bad connection service from them for the past two months. And when I asked why this was happening (via Twitter) they sent me SAIX details to test with (as if to prove that I am the one dreaming up bad connections instead helping me rectify this or providing explanations). I have sent them multiple emails asking someone to contact me as I can only cancel my account online for the beginning of September 2015 and not for the end of July. I think this is unfair as their promises of effective and reliable connections has been something of past for a while now. And they blame it on loadshedding.<br> <br> I find this inexcusable as their customer service this past week has been questionable at best. I have to ask them when they will be getting back me regarding my account and the cancellation thereof. I just get no service from them. Be it connection or personal customer service.
