Telkom

Notice to cancel my subscription was done 12 November 2020 on their website, and for which I received an sms with a reference number. To date, I am still receiving statements of accounts. I have sent numerous emails, for which I have had replies that an agent will be in contact....I am still waiting. How do we as consumers deal with Telkom if they not responding? Who does this get escalated to? So frustrating to deal with no service delivery and incompetence!!!
