iPod touch won't charge

My iPod touch 5th generation will not charge. It is new, bought in August of 2013, been dead since September of 2013. It had a message saying "the charger is not compatible with this device", I ignored it until I plugged it in and it didn't charge at all! I used different chargers. Other chargers work for my brothers iPad mini, he had the same issues but it won't work on mine. I used a friends charger, surprisingly it worked! I don't know what charger she uses but we're not friends anymore so I can't find out. I certainly did not get my iPod wet, nothing happened to it at all!
