Flipkart — Iphone 12 order not shipped

I got this issue please help me, I bought iphone 12 128gb On 2nd October .delivery date is 3rd October but day by day the delivery date is increased but still the product not shipped.when I speak with customer care they just told me to" wait we give a reason for your delay" that reason giving date also extended. I'm shopping in flipkart for more than 2 years, but this time I got a very worst experience.i don't know if it will come or not .if they cancel the product I need to reorder the same product but the offer is ended the price is increased.so, please don't cancel the order please try to process my order.deliver my order as soon as possible.
