Telkom ******* invoicing

I moved to a new property more than a year ago, and requested that my telkom line be moved. The line was promptly stopped, but the new connection never happened. I then proceeded to cancel my line due to telkom never showing up to install the new line. Afterwards I kept on getting invoices. This was due to the fact that telkom did not cancel my ADSL subscription. I then proceeded to pay the outstanding amount (of the service I was never able to use). I then canceled the ADSL online months ago, but guess was, this morning I receive another invoice for R1300, for fixed line rental and ADSL. Do telkom only have incompetence as their company values. This needs be sorted ASAP or I will be reporting this to Office of the consumer protector
