Cancellation process issue

So i sent a request to cancel just my data contract - i visited the store in Rosebank mall, got the cancellations form and filled it and sent it to the ********** email on 28 Feb 2018... I got one reply on 9 Mar (just over a week later) saying there is no attachment from the Retentions Department. I forwarded the email to the cancellations email 5 times after that over the month of Mar 2018. I even went to the Rosebank Mall Telkom store again to query the status and escalate it to which they have sent an email with my cancellation form and drivers licence scan. On 31 Mar i got debited the monthly amount with not reply to my cancellation request. Really?!?!?! Maybe Telkom has no airtime or data to contact it's customers!
