Unable to cancel contract

<p>I am struggling to cancel my data contract with telkom. I went into two different stores to cancel my contract and on both occasions i was give a form to fill out and then instructed to email it to telkom being told that the store can not do it. I then completed the form and sent it to the provided email address only to recieve a mail back that "the users mailbox is full". </p> <p> </p> <p>I then contacted the call center and lodged a complaint only for the call center agent to reply that i need to continue sending the email until it goes through.</p> <p> </p> <p>I have been paying a few months now for a contract that i do not use as i have upgraded to an adsl line (with telkom).</p> <p> </p> <p>I have a total of 4 contracts with telkom and today i received a mail to say that i am in arrears but a debt order goes off every month. </p> <p> </p> <p>Please can some assist me in resolving this issue as i have been on the phone with the call center numerous times holding on for up to 15 minutes not even getting through to an agent. </p>
