Flipkart — Items showing not deliverable at my pincode-700066

Address:

13B Pratham Pally Sarani, Santoshpur, P.O.- Bidhangarh, Kolkata-700066

I am a flipkart plus member and I have been using flipkart from the last 5 years and more. But, I could see for the last few weeks almost 90% of the items are not deliverable/out of stock for my area. My pincode is 700066. I am unable to order anything from the flipkart and also few of the orders that I ordered during the Big billion days got cancelled as well. I already contacted customer care but they can't able to provide any solution as of now. So, I would like to request to fix this problem asap so that I can order the items again. Even though other ecommerce sites like amazon, snapdeal are able to deliver my product at my pincode, not sure why there is such a problem with flipkart. I just want immediate action for this.
