Boat — On account of non-replacement of my boat-rockerz 450

I bought a boat rockerz 450 in the month of june.in the middle of july it started showing bluetooth issues. I sent the product back as per the directions given by the company, but now even after a month of waiting the haven't sent my product. I tried to contact the company many times but never got a reply. My ticket no. Is 1329900. I want a full refund if the company is not able to process my replacement request as the product was not more than 12 days old.
