Shocking, months of being charged after cancelling service!

Cancelling your account with Telkom is nearly impossible. I sent through the cancellation forms at the beginning of November last year. You just get an automated email response, so don't ask any questions. When I phoned the help desk they couldn't help me or record the conversation because I didn't have a case number! We eventually approached our bank to instruct them to cancel any sort of payment going to Telkom. We were still charged for February this year!!! Now Telkom is using a different name to try and get money off our bank account. Sorry Telkom it's just been reversed, you will not get another cent of our money. I have tried contacting Telkom by phoning, emailing, Facebook and Twitter. Yet still no one can help me. Next step is must the consumer complaints council because Telkom clearly lacks ethics and transparency.
