Service Cancellation

I filled in a form to cancel my contract and submitted it at the Telkom Store on 20 Adderley Street in Cape Town, on the 29th of February 2016. I was told it would take 21 working days to cancel and was told my case number was ***6. It's now about 34 working days later and no one has called to finalize the cancellation. I have called the call centre (and spoken to Kamogelo, Hlengiwe and [Email Removed] on different days) and resubmitted the cancellation form and told the matter would be escalated. Nothing has happened and I have had no feedback to date. Please cancel the contract, I don't need it anymore.
