Radioshack did not replace phone with insurance browns mills New Jersey

I purchased a phone and plan and insurance from my local radioshack. The phone and plan is through cricket. My phone broke and i went to get it replaced and they told me they stopped carrying cricket phones and the only thing they could do is give me a gift card for their store. I have been without a phone for 2 weeks now, and what am i to do with a gift card for their store when they dont carry my phone that was supposed to be replaced with the insurance i purchased. So basicly they beat me for a $20 dollar insurance plan. Robert browns mills new jersey
