Pepperfry — Pepperfry is not returning my mattress

Address:	Bangalore
Website:	www.pepperfry.com

I purchased one product "May 6 Inches Memory & HR Foam King Size Mattress by Clouddio" from Papperfry on October 11th, 2022 and have been attempting to return this product while filing multiple complaints with the Papperfry customer service team with no success. It has caused me serious back pain, and I have a gaping problem in my spinal nerve. The mattress cost me a lot of money, and it caused a spinal nerve infection in my back. I'm hoping you'll be able to recognize my issue and send back this useless item.
Below are the old case numbers for reference.
