Best Buy

I just returned from Best Buy Union Square in NYC where I purchased an EZip1000 last August 2010. I've the receipt images attached. I'm very very upset because I purchased this item there because it would be easily serviceable and batteries easily purchased. The agreement entitled me to two replacements of batteries in the two year agreement. Now I am told that Best Buy not only no longer carries your product, but won't even provide me the service. They offered me a refund of the cost of the service contract. I see no reason why I, the consumer, must extend myself to order a battery on your site which costs $135 plus (which is more than the cost of my two year agreement which entitled me to not one but TWO battery replacements).
This does not meet my needs in the least and I will be contacting Best Buy as well regarding my dissatisfaction with their handling of the dilemma. They have my email address on record and take plenty of time to email me coupons, etc. but did absolutely nothing to inform me of this situation.
I have been told I can file a legal claim regarding this matter or that they must return the cost of the service agreement TEN TIMES over.
What I want is a full and complete refund of the entire purchase as well as the assembly charge as reflected on my receipt. They will not oblige. I expect this will have to be filed in court. My writing of this to you is an attempt to see if YOU will refund me given that YOU had an agreement with Best Buy. I will HAPPILY return this item fully. This scooter's battery only holds a charge for little more than a mile now (I weigh 150), and I haven't used it more than a handful of times. I'd estimate a total of at MOST 40 miles on it.
