Impossible to cancel!

<p>Unfortunately I have to log a complaint again on HelloPeter in order to resolve the simplest issue at Telkom.</p> <p> </p> <p>I cancelled my Telkom phone, DSL line and Telkom internet in May this year. After sending the cancellation letter 4 times the telephone and DSL line was cancelled later then scheduled at the start of July. However the Telkom internet is still not cancelled. 3 months later I still receive a bill for internet. I have already logged three disputes and sent 11 emails in order to get this fixed.</p> <p> </p> <p>What else must I do?!</p>
