Bad Service, POOR POOR

I am very upset with Vodacom, I have been using this service provider for years now and they still do not know how to treat their customers. Right now these celeb campaigns they doing matter more than our queries. I called Vodacom last week Saturday with a query on my account (which is actually an error on their side), I was assured I'd be called back the following Wed, which was last week. No one had done that - my account is sitting in arrears for something I don't know about and want to clarify.

I am very angry
