impossible to Link Telkom account to cancel service

Dear Telkom,

I have been requesting one of my service to be cancelled and advised to do so online which should not have been an issue since this is not handled anymore at the shop. Then started the trouble. Not able to link account online as the system does not recognise you of which I phoned telkom to be transfer from one department to the other and being send back to the shop to update my profile whic I did. after numerous calls was given an ********** to help me link the account which response time is a day to two after each queries or relaunch( 4 at this stage ie 8 days waiting). They provide a number I should use to link my account which did not work either to which they responded my passport number was not update ( which I updated at the store days ago). BIG discrepancies as system not synchronised. Nonetheless I forward a copy of my passport and still at this date I cannot link my account to cancel one service. Can you exceptionally help me link my account and cancel my landline/ADSL. It's been almost a month going back and forth. Which options Am I left with because I will not accept further debit
