Flipkart — Gaming laptop not delivered since a week, keeps getting delayed.

I have ordered Msi gf63 thin 10sc gaming laptop for 55000rs on 8th October in big billion sale.. It was supposed to be delivered on 11th but due to logistic issue it postponed to 14th october. Today it is 15th October and theres no tracking update or any notification from Flipkart.
The contact support is useless they keep postponing, first they said it will be delivered before 14th, now they are saying before 20th. But theres no confirmation of a delivery date, and the tracking isnt even working its still showing the last track from october 11th..
