Telkom Accounts Department CANT DO MATH!!!!

My Subscription Service with Telkom was due to be ended in END 28 Feb 2015. I phoned in Jan 2015 to cancel with Telkom. I phoned 1 MONTH in Advance to Cancel ANY AND ALL SERVICES AND SUBSCRIPTIONS WITH TELKOM. Your Call Center lady said I MUST phone back on 05 Feb 2015 to Cancel. I did EXACTLY that!!! My SUBSCRIPTION AND SERVICES WERE TO END 28 FEBRUARY 2015. My Bill on 8 February 2015, I OWED Telkom R198.10 which I AGREE 100% with!!! Bill was For Feb 2015 to be Paid by 02 March 2015. We moved out Friday 13 February and Disconnected EVERYTHING!!!! I was then Told that Even though my Services were scheduled to end 28 February 2015, I still had to pay for 1 Month. So end March I Owed Telkom R741.36. First of all I think this is BULL ****T!!!!!! How do you Charge me 1 Month Additional Services and Charges? Then, your GENIUS Call Center never Cancelled my Services so I just kept on being Charged and Charged and Charged every month!!! On Mays Statement, you tell me, I owe you R1882.40. Then on June's Statement you tried to rectify the Account, but still *****ed it up so bad, because I'm STILL BEING CHARGED FOR STUFF!!! I OWE YOU R198.10!!!!! THAT'S IT!!!!
