Can't Cancel my Account

I've had such a terrible experience with Telkom! I cancelled my ADSL subscription with them last year, and yet they continued to bill me without telling me what service they are billing me for. I have refused to blindly hand over my money, so Telkom has blacklisted me and suspended my account. After emailing them and trying to find out what is going on, the only response I received was that my account is in arrears. Not one person has tried to help me. With my credit record in ruins I've now paid the amount owed, but now I can't cancel the account as it has been suspended. I will now be billed again and go through this entire process all over again despite me having cancelled nine months ago! It's no wonder they make the cancellation process so hard; if it was easy, they'd have no clients left! Nothing more than a bunch of *******.
