Cancellation not being done

I have a lot of both good and bad things to say about Telkom. My experiences have always been fairly positive but, recently, they have been letting me down in a very big way.

I am trying to cancel a month to month contract. I have gone through the correct channels, done the paperwork in store, and waited for my month's worth of cancellation period.

After the 30 days passed, my final payment was meant to be made. A month later, I am debited again. I phone their customer care, and the person who helps me apologises and promises to rectify it with immediate effect. I am told a credit will be passed to my account. I'm pleased with this service and give the agent a good score.

30 days later, and the debit order goes off once again. This is not acceptable, Telkom. I am not paying you for my good health and I am quite disappointed that my cancellation is still not processed. Please fix this and refund 2 months to me - directly to my bank.
