Worst service ever

Telkom do not even deserve a star you guys keep on debiting my account even though my account *** is cancelled you **** me off and i will never ever make use of your service again. Fix it on your side my contract was cancelled in December the sim card stopped working in December i am not paying for something i do not have. Worst service ever!! I will never use your services again in my life you have so much complaints about contracts not being cancelled why don't you start doing your jobs and stop debiting accounts and stop sending me invoices and new deals i am not interested!!!!!
