Feeling ****d!!!

I feel like I consented to *** with someone and ended up having *** with someone else!

I upgraded my contract with @Vodacom a few months ago! I then noticed that I am being billed for an amount I did not consent to, I let it go the first months because I thought its charges relating to the upgrade. It continued. I then called @Vodacom to sort this out. I was told the reason for the incorrect billing is because I am paying for the laptop and wifi router separately. This is not the deal I was sold I was told that that the laptop comes with the wifi router for R359 a month! I was then given a reference number and a promise the matter will be investigated and someone would come back to me. Silence. Today I call @Vodacom to follow up and the first person I spoke to tells me that the resolution on the system is that I should call the store where the upgrade was activated. I am confused because my business is with Vodacom. He them forwards my call to upgrades. They tell me the same thing and I am angry because until that moment I thought my business was with @Vodacom not some third party I don't know. Secondly, why was this not communicated to me? Why was I not informed that I no longer have my business with Vodacom or that my details had been given to a third party.

Seriously Vodacom!!!
