Microsoft "We have your money, screw you!"

My Xbox 360 stopped working today. I followed all the instructions on the page...http://support.microsoft.com/kb/907534 .

I followed the advice they give on their page.
Unplugging and replugging the unit entirely as stated in their page only resulted in tripping the circuit breakers in my house.
I then disconnected the hard rive and this did nothing to solve the problem.
I then called customer support only to be told after five minutes of a call I have no doubt I will be charged for even though it is an eight hundred number, that they claim it was never registered. I know I filled out the paperwork.

The 360 is now in the trash.
It will stay there.
Microsoft has once again found way to screw a customer.
