Refund monthly deducts

I contacted Telkom in October to cancel my ADSL/Fibre as i had to move in with my mom cause of a medical sickness. The last part of October i was in Hospital, and then from November, December, January i have been living with my mom. I mom moved out of my flat (which had the Fibre) end of October. 1st - My contract has not been cancelled even though i requested it be done in October, how can i pay for fibre if i dont use it? 2nd - My monthly fee with Telkom is R806.02 pm, NOW suddenly im receiving accounts for the amounts: R2455.61, R3297.96, R4152.77 Please cancel my contract as previously requested in October and refund me all payments that were deducted from October to January. i have not used Telkom fibre for 4months
