Pathetic and Utterly disgusting service

I have a number of contracts with Vodacom, I have lodged a query pertaining to the fact that I do not have a network coverage in my area in August 2018. This problem has been going on until now when Vodacom's network department did eventually informed me that I am outside the network coverage in my area, with that confirmation, they opted me out of the contract and they immediately initiated the cancellation.

A consultant from Vodacom, Slindile, contacted me and we agreed that the contracts would be cancelled and deactivated on the 31 March 2019, and also that Vodacom would arrange to the collection of the device, as well as the refund from August 2018.

To my surprise and disappointment, my contracts are still active despite the fact that I am unable to use the service. I tried calling Vodacom today for help; it was a painfully frustrating experience to be sent from pillar to post by Vodacom's consultants, the service that I received today from Vodacom was devoid of any professionalism whatsoever. To compound the matter, I endued that pain and the unfortunate part is that I am still not helped by Vodacom, I am still forced to pay for a non-existent service; I am not sure what to do or go about this problem.
