Cancelling contract with Telkom is a nightmare, would not recommend them

Spoke to Gerald then Ntabiseng who seemed clueless about my account and gave me conflicting stories. Im trying to figure out why Telkom is charging me after I cancelled my account on the 20th July. Was told that it takes 21 working days to cancel the contract. Had an amount of R254 going off my account in October which I reversed since I cancelled this account. I'm now getting another statement for the reversal?????
