Sony refusal of repair Internet

 We bought a ps3 2-3 mnths ago and it died no lights, nothing. we purchased the extended warranty which  brought the price to around $400, we sent it back to playstation for repair and they sent it back saying they wont touch it because they found a dead roach in it, if a dead roach kills the system thats 2 mnths old why are they $400? should be $10 and desposable. heres the harsh part, we called playstation and talked to a manager, he basically screamed at us and argued that we have a nasty house, after butting into our questions "rudely" and then yelled more and said have a nice day and hung up on us....Is this right and wh didnt the replace it? Out of all the problems ps3's have, how can they say A dead roach caused it?????    sounds like a loop hole for sony to stay rich and rip off their consumers along with billions of dollars. my name is carol p**** **** sw decatur alabama 35601 phone is (((redaced))). help my email is
