Boat — Regarding my BOAT rockerz 255 NEO delivery

Hey, I still haven't received my package which was supposed to be delivered by 29th of this month. My order number - 2656333_BBLR506981 . I request you to immediately get in contact with Kerryindev express which you have selected for courier services. I received my BOAT 255 pro+ whose delivery was 30th august and it was delivered by amazon shipping and that too on time. I still have no idea why they haven't delivered as they have received the package at PMC branch. Now they are showing that it will be delivered by 30 aug - 1 sep. But I have to travel abroad by 31 august in evening. I would have to cancel this order if it is delayed this much. That courier service is not picking up calls and no updates from your side as well.
