Telkom refusing to cancel my Telkom line and ADSL

After receiving confirmation about the cancellation of the Telkom line and the ADSL portion, Telkom continues to bill me. I have proof that the cancellation was received and I even took screen shots of the chats I had with Telkom representatives where the conform the cancellation and date when it will take place. I have email ********** to ask that they please look into the mater and that they complete the cancellation. I am giving them sometime to respond then moving to ICASA.
