Sony India — power bank by sony

Address:

New Delhi, Delhi, 110025

I purchased a sony power bank few months ago, it was working fine, but now it is not getting charged. I left it charging overnight for approx 10 hours but it charged only about 30% it is mentioned as fast charging power bank in the description. I am very disappointed by the company's service. I am a practicing advocate in tis hazari court, delhi. And i seek help as being a consumer of flipkart and protection under consumer protection act.
Thanks!
Regards,
Ramsha
