Fry's Electronics

I bought a Panasonic microwave on June 28, 2010. It is 1.2 Cu. Ft. counter top white, NN-SN667W. Price was $139.99 plus 7% sales tax; Invoice #3162467. (I spent almost $300 at Frys that day). I connected the microwave and it worked fine up to 45-50 seconds. Any longer than that amount of time, the circuit breaker would kick off. I had an electrician (Dave Townsend [protected]) check out the wiring and the microwave and he moved it to another outlet. That circuit breaker kicked off, too. The microwave got very hot on the outside top and we could smell that it was too hot. It is supposed to draw 12.7 amps, but his equipment showed it was drawing 16.7 amps. I have called Frys Store #[protected] at least four times today and was treated very rudely and hung up on each time. They put me on hold and did not handle my concerns. The main problem is that I do not have the original box to take the microwave back. They are telling me I will be charged a 15% restocking fee or have to make an even exchange. I do not want an exchange and should not be charged ANY fee for a defective product. I plan to return the microwave but will not pay the 15% fee for not having the box. This is harrassment on Fry's part and is no fault of my own.
