Telkom - You pay for nothing and even pay to cancel nothing

I have been struggling with smart broadband wireless from Telkom for months. I pay R1138.00 per month for absolutely no service. I have complained numerous time without success. Thankfully one of my lines expire in three days and I have asked for cancellation. The other line, which is also the most expensive and problematic only expires in June 2018. I am not getting any value or service for this R739.00 I pay. I have probably had 2 days intermittent internet connection in the last two weeks. I can't use my printer, access emails, surf the net or even use my Apple TV. What am I paying for. To add insult to injury Telkom expects me to pay a cancellation penalty and that for a service I am not even having the benefit of using. I am thus being forced to pay for absolutely nothing.
