My port broke on my Evo and sprint told me the same thing, user damage. untill now I was so happy with the Evo. I always thought the port seemed awfully flimsy.
Didnt HTC count on everyday use? To top it off sprint didn't have a record of me opting for the Total protection which I did get. They're looking into. Fortunatly I found an external charger and extra batteries on Ebay since the only way to charge the phone is to replace the battery.
