Jio mart - A certain product s return was declined

My product was refused for return without my knowledge. I didn't receive a note or email informing me. My issues with this product are as follows:

*) The product I received frequently had one earpiece discharge more quickly than the other due to a malfunctioning battery in the earpiece.
*) The company claims that the battery will last ** hours, but I am only getting half that amount. I question the product's originality.
*) A charging cable was stated to be included in the box, but I didn't receive one with my purchase.

I'm still puzzled as to why you sell false information on your website, despite the fact that a * day return policy was clearly stated. You are deceiving your customer, which is unacceptable. I hope you will investigate this matter and promptly return my defective product.
Thank you very much.
