Replying to XBOX GOT RROD!!!!!!!!!!!

alright so on sunday i came home from church and decided to play the fifa 09 demo which is the shiz.  I turn it on the there she goes. three flashing red lights. i call xbox and they take me through some trouble shooting steps-- still doesnt work.  I finally talk to a real person and ask if i can ship it in to get it fixed and they said my warranty EXPIRED A WEEK AGO AND IT IS GOING TO COST ME 100 TO FIX IT!!!!! I always thought they did this for free.. so im just done with xbox now. sad day
