Boat — so much delay in replacement product delivery

I already submittedy my complaint but no use even they resolved the problems of tge custokers who complained after me. So i am requesting once again. I claimed warrant on my boat ear phones at the start of october even the pick up was taken lately. Finally it showed replacement product issued on october 22nd it has been 10 days still no change. They even not replying to emails and not attending calls. Why this kind of bad service. I need my product back as fast as possible. Otherwise they will loose a customer. Please help me fast
