Hhgregg Premium service policy, false advertasing, lying to customers, phony computer records, horrendous customer service. Clearwater, Florida

I have been waiting about one month now, for Drew Isaacson of the Clearwater store to contact us. We spent $250 on a service policy on an $850 3d tv. We have our receipt that states this. Now were being told we are only being offered  a $600 credit!!! A month ago we went into HHgregg locatedat 2669 Gulf To Bay Blvd Clearwater FL, 33759. Where we  purchased this tv  to sort this out .. Drew Isaacson took our information and was supposed to contact corporate and get back to us. It has now been a month. I called today and he no longer works there. Neither does sales person who sold us tv. When we bought the television it was not sold as a bundle to get two pairs of glasses we bought the five year service policy and also had to wait till the next week for shipping so we would get glasses for free. Even on our receipt it says glasses and then the price is blank . We would never have spent $250 on a $640 tv's service plan!
I can fax you the receipt if you would like. It has been three months of nothing but a headache and I thought that is what the service plan is supposed to prevent? Then to not be contacted by a manager for over a month is not good costumer service in the slightest. thank you for reading this.

Desired Resolution:

A replacement credit for price on my receipt of $849.99 because that is what the service policy states in their own writing. I have the original receipt, no matter what their system says.  They really should also talk to their sales people about lying to costumers so they get a bigger commission on a lie. Which then again they have such a high turn over/fire rate  it seems because the person who sold us television no longer works there, neither does Drew Isaacson. The final total
on my receipt with the $249  Premium service plan is $1,176
