Vodacom biling me for Services i Cannot access

Vodacoms outbound sales personnel called to upgrade a contract in Oct/Nov 2017 The device was delivered but with no sim card although we requested one. we have made follow-up calls requesting a sim card, which they promise they will deliver but we still have not received. Its been months now that we are being billed for Data and minutes that we have no access to because we do not have a sim card. they keep promising they will deliver a sim card but they dont deliver. How can you charge me for a service every month that i am not using, this feels like i am being ****** by Vodacom, this is actions of a *****.
