Cisco warranty

Hi, I bought a C3750G-12S which is now end of sale on cisco website. This device is now defective. Since I bought it from a reseller and not directly from cisco, cisco is refusing to take it under warranty and tells me to have the reseller take care of it. The reseller doesnt wan't to hear about this device since it is end of sale. According to cisco website, end of sale means the device is still covered for 5 years. My question is: Is it normal for my supplier to refuse to take it under warranty ? Is there (from your experience) a chance I might get cisco to deal with it ? Thanks Laurent
