******* of DATA! SMS Charges! No service!

I am so sick of being ****** by Vodacom. In May they send me an account for R3000 for smses to a number I don't even know. I queried this several times logged 7 service tickets each and every time the ticket is closed without any feedback. I have a call and data limit set on my account and every month my data charges runs to R1000. I get no notifications on how this charges are accumulating. I have wifi at home and work and cant understand how this is happening. I logged a request 3 weeks ago and haven't heard from Vodacom. This is ****************. I am going to report this to the ombudsman. Every month my account is over R3000 for I don't know what. Customers are ****** of data, charges accumulates and there is feedback on any of this.
