Vodacom Bloatware

I bought a new phone which was not branded to any network.<br> <br> The moment I inserted a Vodacom prepaid sim card, several Vodacom apps were installed without my permission. My wallpaper was changed to a **** Vodacom image and all my setting were changed. All this was changed without my permission.<br> <br> I am unable to remove the Vodacom apps. This is very sneaky of Vodacom. I would like to know how to remove the apps and restore my original settings. The phone was not bought from a Vodacom outlet so Vodacom has no right to add their branding to my phone. <br> <br> If I don't receive an immediate response, I will take to this to the consumer council, ICASA and the newspapers so that the entire of South Africa becomes aware of the underhanded tactics of Vodacom.
