TELKOM TI - SBSA Dialup

After several attempts, over several months, to get my TI - SBSA Dialup account cancelled, since January 2018, Telkom is still billing R69.00 every month from my bank account. Several calls were made to 10210 - every time waiting for hours to speak to a consultant just to be cut off again. I've visited the Telkom store in Lakeside Mall on numerous occassions and all they could do is sending a mail to someone who would call me back, but never did. I have sent queries to the Escalation Centre and received an automated reply to confirm receipt of my email, but I haven't received any response yet. The balance on my bill is currently 1320.76! I do not even use the DialUp account! Thank goodness I never signed up for a debit order facility, or this would have been paid from my account. How difficult can it be to get this account cancelled? PLEASE HELP!!!
