Dayside Windows And Doors

Had multiple windows replaced. Very happy with the sales rep and install teams as they were very professional. I noticed this spring that my bathroom window on my second floor cracked on the inside of the exterior pane. i took pictures and sent an email to the head office but got no response. I had to get my sales rep to intervene. When i did get a response i was told it would cost me almost $400 to replace as it had been just over the year glass warranty. The cheap builders grade window lasted 14 years without any cracks. The brand new higher quality window broke outside a year and its my responsibility. Is it just me or should a new window last more than 1.5 years?
