Boat — Replacement undelivered

My boat stone 230 speaker was picked up from me on 28th july and i was promised with a replacement within 20 days. my ticket no. is 1337499 and i havent received my replacement yet also the company doesnt answeer any call and never replies to emails..there is no update about the issue in their website ticket tracking and it is very disgusting. i need my product back or atleast refund my money because the product wasnt used even for month and it needed warranty claim.
