I have ordered iphone 13 on big billion day sale (22 Sep 2022) with full payment. After order confirmation delivery date given as 4th Oct 2022 but product is not delivered on that day.

I have raised an complaint against this issue to flipkart customer care so they have given new date of delivery as 6th Oct 2022. agine product not delivered on 6th oct. agine i have raised an complaint than this time they given date of delivery as 11th Oct 2022 still product is not delivered and its not yet shipped.

Same product get delayed by flipkart 5th time after i have made full payment and product is confirmed by supplier. Multiple times i have tried to connect flipkart grievance team, unfortunately no response from them.
Every time when i called to customer care they are telling me that we are looking into this issue but no solution is provided by flipkart.

Please look into this issue and provide some solution, i have made full payment for iphone 13 and almost 21 days completed but not received any positive feedback from flipkart.
