Pathetic service fro Telkom - Cancel my Line

Called Telkom on 4th December to downgrade my plan from SmartVoice unlimited at R 599 p/m to SmartVoice basic at R 199 p/m and the request has not been completed as yet. I am still paying R 599, i called today for my outstanding amount and the bill is at R 615.75, how come, i dont even get my statements.
