Im being held histage by Telkom

Why am i being held hostage by telkom?!?! My contract expired but you keep debiting my account... Why is it MY duty to let you know my contract has expired? You keep calling me to sell me a new contract but when I say i need to cancel my contract you cant help me... Instead im directed to the portal where i cammot canel my contract, and when i call you redirect me to the portal and round and round we go!!! Im beyond ****ed! Your service is trash... I only matter when you want my money... My telkom sim hasn't been working for the past 2 months and yet i still have to pay?!?! *** THOUGH??!
