Query: Bad support and waranty

The MFC-8460N worked well for two months and I was very happy with it. Then one day it just break down, and will not power on. I called and they said they will send a replacement; so I waited ... About two week later, not receiving the replacement, I called back and they said they had to verify the address. Another two week or so went by, still not receiving the replacement, I called and again they wanted to verify address again. Then again, still not receiving the replacement, so I called and for the third time they again needed to verify the address. I demanded to talk to the manager. He promised to send the replacement overnight; and I received the printer within two days. Unfortunately the replacement did not work either -- the paper kept being jam every single time! That would be the last Brother printer I would ever buy.
