Boat — warranty replacement delay issue-one month still no response

Hi,
My ticket number is : 547042
The worst customer service, no one will take more than one month and till no response...
I made a replacement request of boat rockerz 255 bluetooth earphone on 14/09/19 and reached at service center on 02/10/19. And last status shown was "replacement product issued" on 02/10/19, after that no status updated on ticket number and no mail or message update. I tried to call several times on customer service support number but no one answer the call after long long waiting time. It is almost one month till now they don't dispatch the product. And from last 4 days on wards when i tried to contact customer care "we are leave today" i don't know how many days they are in leave.
