Recently upgraded to the new iPhone, and my sales rep (Bill) covertly added Vz Navigator ($4.99 monthly) and Protection - iPhone ($10 monthly) without even mentioning these, or asking if I wanted them. I only discovered them later while reviewing my bill. I'm unsatisfied with my experience. Next time, I'll go to one of the kiosks at the mall.
