Flipkart — All products showing not deliverable at my pincode

I have been a premium customer of Flipkart since years. This BBD sale I have bought a lot of products. But just after the BBD, all of a sudden all products are showing 'not deliverable in this pincode'. That's really irritating. Even the seller delivered me yesterday is also showing the same message. I have uploaded the ss of one such product which I bought during BBD and now showing can not be delivered. I have mailed in customer care, no reply. I have talked to the cc executive and was assured that the matter will be solved but still it is not. Please look into the matter asap.
