Exide Batteries — unable to claim warranty due to covid-19 lockdown

Address:

Datta mandir road, Malad east, Mumbai City, Maharashtra, 400097

I have bought the battery on 17th april 2017 and its just a month away when the warranty period of my battery will get expired. The battery got dead on 25th march 2020 and from that day i'm unable to visit any shop to claim the warranty as government has asked for a 21 days lockdown and then i won't be able to claim the warranty. Also these batteries are expensive so it will cost me huge amount of money if i need to start my car with a new battery.
Please suggest what can be done now
