Please cancel my telkom line

My husband tried to call the Telkom call centre to cancel our Telkom line, but was put on hold for so long, that he gave up and decided to rather go to a Telkom shop.<br> <br> He went to the Telkom shop and they too were unable to assist, they gave him a form to complete and said to email the form and his ID to an email address listed on the form.<br> <br> Today I emailed the form, just to get an automatic reply saying that the mailbox is full and can't accept new messages.<br> <br> Meanwhile we are paying for a service we no longer want.<br> <br> Can somebody please cancel our Tekkom contract?????
