Unable to cancel a service

I have a Telkom Smart Home Premium package with inclusive 50GB ADSL data. I wanted another 50GB so Telkom added a Softcap (100GB) a few months ago.<br> <br> I now want to cancel just the Softcap (100GB) and keep the SmartHome Premium but it is proving to be impossible. I have already made 7 phone calls, each lasting between 20 and 40 minutes but am still unable to process the cancellation.<br> <br> Either I can't get through or the consultant tells me I'm at the wrong place or the call cuts off before completed or as today, Telkom no longer has a cancellations department - I must send an E-mail! <br> <br> Within 5 minutes of each other, one consultant tells me to call back to get to their cancellations (they can't transfer) and when I call back another consultant tells me they no longer have a cancellations department and I must E-mail.<br> <br> By the way, I also send a cancellation E-mail a week ago (to address given to me by one of the previous consultants) and have heard nothing back at all.<br> <br> What the kind of business is this?
