Bad customer service

What a poor service I've received from your consultant "Nestar". It makes me wonder why I'm still pursuing your services. I don't understand how my phone keeps joining subscriptions while "off" makes no sense to me. And while it does not make sense to both myself and the consultant, Vodacom will not be refunding my airtime. Where do I go to when this is the only resolution I get from the consultant?!
