Query: Phone died and Nokia failed to honor the warranty

This was a great phone until it died after a few months of use (no signal reception.) I thought that was not a problem since it was under warranty. Boy was I wrong. Nokia's warranty repair center took several weeks to update the software return the phone to me unrepaired. Then I sent it back and they returned it unrepaired a 2nd time. This time they claimed they would not repair the phone at all since it had mysterious "corrosion" which they hadn't noticed the first time. I will not buy a Nokia product again due to their terrible warranty service.
