Impossible to cancel contract

I have been trying to cancel Telkom mobile services since November. It's now three months later. Your service has been worse than pathetic. And from the other complaints not receiving any feedback, I can see just how much that bothers you.

In November I made a telephonic cancel request, after which I received forms to fill in , and an email to send the forms to. I received no response after doing this. I phoned again to enquire. I was told to mail again and ask after 21 days. Which I did, after again receiving no response, the second time I sent a mail, I received a mailbox full notification. Once again, that says a lot. I went to the store December, January, and now again. And still, STILL I get invoiced for services I no longer need or want. Let me make it clear, this is bordering on out right *****ing. Get your act together and sort this out. I don't have time to go into your pathetic stores anymore, just be told I still need to wait. Your last worker at Irene told she would phone, which she never did, and I have yet to get hold of them. You obviously have no concern for your customers, and I will gladly pay more at any other provider before ever using you again.
