Bests & Worsts Reviews from Amazon

Broke down after 3.5 months of using This has been working fine until after 3.5 months of using, the left side (the one I use for cooking the most) completely stopped working, the right side is burning really low and slowly. Mind you that on the packacking says “limited 3 year warranty” Now, that the return window is closed (only a a month since the day it was purchased). So am I stuck with this broken stove? Please give me an appropriate solution.
