Refund not done

I cancelled my 8ta contact in September. I was told my contact ends in December. I sent all the paperwork for cancellation. I was contacted by someone and they said the refund will be done for my January and February instalment within 5 -10 days. This was in February. To date, no one has contacted me. I keep phoning telkom, but keep being told someone will call me. I have a case number for the refund, but that means squat as no one at telkom is interested in it. If this is not sorted out, I will go to the ombudsman and the consumer council.
