Boat — Request for replacing product Boat Rockerz 385v2 Active Black

Address:

Boat company

I have purchased Boat Rockerz 385v2Active Black using Cred platform which was delivered on 27/07/2021 having one year warranty period Now it's not working properly so I'm trying to replace it from last 3 months. I have sent various mails to Boat but every time they declined my request citing that I don't have proper invoice. I got this mail only when they deliver the product (Snapshot enclosed here with).
