My Boat headphone got unusuable within the warranty period so i claimed warranty.And Boat shipped the replaced unit via Delhivery.com and initially the Delhivery live tracking feature on their website gave the 11th June 2022 as the time by which the product will be delivered but they didn't deliver. And the next day which is 12th June their website showed that the product would be delivered by 12th June and on 13th june, the Delhivery website

And now it is 7 pm 14th June 2022 and they still haven't delivered it.
