Boult Audio — boult earphone not work

Address:

At/Po-Balichandrapur, Jajpur, Odisha, 754205

I bought a wireless earphone from flipkart but after 2 days, it didn't work. I call flipkart customer care but they told to contact boult customer care and didn't help me. I tried so many times to contact boult customer care but they didn't respond. If flipkart sell any product, why should not they provide the warrenty.
Plz help me to give me justice.
