Billing and *********** staff

I am extremely annoyed and disappointed with telkom service. I cancelled my account in March 2017 because my contract came to an end, but till today my account is still been debited even though i don't have a mobile contract. I called telkom this morning and to my surprise i was told that i have only suspended the sim card and did not cancel the contract. Even after i have explained so many times that my contract came to an end and i went to telkom eastgate mall branch for cancellation, the call centre agent still insisted that contract was not cancelled. As it shows that not only are staff at Telkom not paying attention to accounts that have been cancelled, but they are also actively *****ing funds from customer accounts by ignoring cancellation requests.
