Line suspended

Last year (September 2018 - 8 months ago) I wanted to take out the unlimited package with Telkom. They had problems and I had to put in a cancellation request, because I was with a different service provider with my data package. After a few days the problem was sorted out and the cancellation was withdrawn and I could work again. Have been for the past 8 months. Now suddenly my line is suspended. With life-chat they told me it was because I put in a line cancellation in Sep 2018. And all they tell me is that I must phone 10210 or 10213 or the toll-free number to speak to accounts. They just cannot seem to get it, that I cannot even phone any of that numbers. Not even the email gets delivered to the email address that they gave me. I am sure not going to use my cellphone to contact them. What will by bill be after holding on for hours for somebody to assist. They still billed me for the account every month, even for this month. I asked life-chat if they can get somebody to contact me, but their reply is that they do not assist with account inquiries. Not even willing to go that extra 10cm. How hard can it be to pass a message along to the department that must sort this out? I want Telkom to sort this out immediately.
