Cancellation without my permission

At 7:30AM yesterday morning, my ADSL suddenly stopped working. This is not an unusual occurrence. When the ADSL was not back by 9:00AM, i decided to log onto Telkom's website to log a fault. Entered in my landline number, and i got informed that there was a system issue and they could not log the fault at this time. After attempting this multiple times , i eventually sent an SMS to Telkoms Fault reporting SMS number - 30591, for which i got no reply. So i had to phone the customer service number who, after informing me that they would need to send out a technician, told me that my ADSL line had been cancelled on 10 April (almost 2 months ago). I never cancelled it. I never received any letters / SMS / Emails informing me that it was cancelled.

Now, i have to sign up AGAIN for something which i have had for over a decade. Telkom, please tell me HOW can a package that i am paying for, get cancelled without my permission???
