3 Days out of warranty

When I received my phone Autopage said I had 2 screen replacements. I have a Galaxy Note 4. Today they said to me the phone is 3 days out of warranty, it only has a year warranty whereas the Note 3 (older and less expensive model) has a 2 years warranty. I am so disappointed I wanted to cry. 3 Days, the staff was not helpfull at all and the manager was very neverminded. The warranty was misleading and poor service. They couldn't even help me with a extended warranty, I mean 3 days!
