Bad product, ineffective customer support, poor service

I signed up for a subscription but couldn't login into Showmax after signing up (Vodacom billing option). Used live chat to troubleshoot. After an hour of talking with the agent I still couldn't login. Was told I would have to change the browser on my machine; something I was not prepared to do. Advised the agent that I wanted to cancel the subscription and should not billed since i was never able to access the service. After far too much back and forth with the agent they eventually agreed to escalate the issue to a supervisor. I also complained on twitter. The following day a supervisor called Masera (who took a very peremptory and facetious tone with me) eventually and grudgingly agreed that they would try to cancel the subscription and reverse any charges that would have accrued and that they would email me confirmation. I received an sms from Vodacom to the effect that the subscription was cancelled. I have nonetheless been charged for a subscription for September - this has not been reversed. Masera did not email me about this and no one has responded to my further query about this on twitter. I have wasted 3 hours of my life trying to cancel a subscription - and reverse a charge - for a product that was never accessible to me. Truly appalling experience.
