Pathetic service

I have cancelled my 2GB wifi in February 2018. To date this still has not been done. After numerous telephone calls with confirmation that it has been done. I have sent emails whereby Vodacom does not bother to respond. Yet i received another invoice for May which still reflect the amount owed. Ntombi Mbatha what did you do to solve my enquiry?? All empty promises and no delivery on service.

I want the wifi to be cancelled backdated from February 2018 and the amount that was debited from my account from Feb to date to be refunded.
