Phillips — phillips is refusing my warranty claim for m/n dlp6006b

Address:

Bangalore, Karnataka, 560048

I purchased the phillips powerbank from flipkart, after using several months its otg cable which came with the product is not working. I tried contacting phillips by registering the product on their website and to claim warranty i even send the email via their platform to generate the support ticket (#222696), and tried 10 times on their given number[protected], but they never responded.
I sent email again, but no response. I called on general customer care but no help i got.
I even gave them proof of purchase in the send email ticket.
The emial sent and receive was to philips displays & audio consumer care team (India).
I need either they repair my powerbank and replace the otg cable or they provide me with new powerbank or they refund my money.
I attached the original invoice, i also sent this to phillips india.

General number:[protected], i called this number but no help i received.
