Request to cancel line not being actioned

I was transferred from Knysna to Herm**** and need to cancel my Telkom line. I forwarded my request to cancel the line on 14 December 2015. When I phoned on the 21st of Jan 2016 to confirm that it was actioned I was informed that it was not and that I need to send the request through again. I forwarded the request again on the 21st of Jan 2016.<br> My bank account was still debited with the monthly account on the 26th of January 2016.<br> Kindly cancel my line with immediate effect and refund any funds charged.
