Inept Cancellation Service

After calling Vodacom three times in Februrary to attempt to cancel my contract, which has reached the end of it's life-cycle, and being informed by the call center agents that it has indeed been cancelled for 01 March 2018, I find that it has, in fact, not been cancelled today and I have yet another invoice due for end of march.

I am shocked that the Vodacom systems are so poorly implemented that you cannot even cancel a contract with them.

I requested that my contract be cancelled at the end of February and was told it will be done as such. I refuse to pay another cent to Vodacom.
