How do I get Verizon Wireless to honor what the store personnel told me, which I agreed to and was reflected on the estimate of my first monthly bill?

Question

I previously had a $60 per month loyalty package with 2 GB for my smart phone.  On 1/31/15, I purchased a tablet at the store to go with my  phone, because the sales rep  told me she could reduce the total monthly charge for the phone to $30 per month at 1 GB and add the tablet for $10 per month. The store specifically said the total monthly charge (before taxes and fees) would be $40.  I just received the first bill, where the monthly charge is double at $80.  The Verizon supervisor said he would credit the first month overcharge, but that I would be stuck paying the doubling of the charge for the remaining time period.   Totally unacceptable.  I have been a Verizon customer for years and am completely dissatisfied with Verizon's failure to honor their agreement.

Answer 1

What are you talking about?? This is what he said above:
I have copies of the two electronic receipts signed by me - one for the purchase of the tablet and one for the monthly charges.  Neither receipt references an extra $40 "line access fee."
Hence he has a receipt for the monthly charge which does not reflect an extra $40 bucks... So you are saying employees should not be held accountable for misrepresentation? And its the customers fault if its not reflected in a customer agreement? Verizon is liable because it was their employee.
