Billing after Cancellation

Hi Opened a telkom mobile data account and cancelled the month to month data agreement in November 2017, I am still getting deductions from telkom via debit order and they are not in any way trying to assist with this matter. I have made numerous calls where a call back due to escalation has been promised and yet no one has reverted back to me. I have to continuously use my resources to call and follow up.

this is the first recourse outside of telkom before heading to the telecoms ombudsman.

I regret ever taking out a package with them
