Planet Nissan

I purchased my 2011 nissan altima on this location on 2013 which they give me 100k waranty for certified pre own. Now i have a radiator leak and my car still under 100k so i call planet nissan to find out If still have warranty of my car which they told me i did. Then i drop off my car today and again ask if my warranty cover everything then speaking to advisor Joshua he said yes. Few hours later I received a call from Joshua telling me that my warranty was expired on june so i have to pay $1300 to fixed a radiator and termostat. REALLY $1300??! I can smell they try to rip me off.. Thanks Planet Nissan!!
