failure to cancel

In December 2015 I have called telkom to cancel my uncapped data and was told it will be cancelled on 9 Jan 2016. Come 9 Jan still not cancelled. Wrote to hellopeter and was contacted by telkom Khuthula Sizani to fill in a cancellation form and email. This was done on 19 jan 2016. To date not cancelled. I have already signed up with another service provider and paying twice. Portia calls me and transfers me to fameeda who says I must send a request in writing. ***! This was done in Jan. This incompetence is beyond belief. I will seek legal advice and forward my service provider invoices to telkom and will be emailing icasa.
