Samsung — Samsung Galaxy A505F

Hello, this is pratik telgani i had purchased my handset on 9th of may 2019 and i faced the network issue related to my handset within the warranty period and i have already filed it through online requesting to replacement. Due to lockdown i was not able to go to the service centre. And after few weeks of opening of lockdown i went to the service centre to claim my warranty but they refused saying we have given 14days of time to calim and u didn't show up in dat period where as the extended time was not at all informed either through mail or message. Now the are refusing to claim my warranty
