Vodacom contract never ever again!!

Hi

My name is Lucas . I have an issue with Vodacom regarding my contract which was supposed to end in January 2018. I had a couple of months were I did not make payments but made those payments in full in july. Since January I have been told that my account is on a month to month contract, BUT I am STILL paying the full amount of the device and services!! Every month I pay I am told my account is in arrears and gets blocked every month of the same situation! I am now paying Vodacom for 28 months with the same bull**** story!! This is just worst service provider ever! Calling agents is a waste of time they all keep transferring me from one agent to another without any assistance or explanation to the issue.... I does me missing a couple of months payments, which are fully paid by last year extend my contract without my consent even..
