Flipkart — Repeated delivery issues.

I have ordered an iPhone on 24th January. The delivery was promised for 2nd February. It did not reach me. The shipment reached the nearest hub at 2pm on 3rd February and showed delivery for 4th February. The hub is about 5 or 7 km from my office, where the delivery is to be made. On 4th the delivery did not reach. On contacting and complaining in various different ways, I was assured delivery by 5th February 6 pm. That too did not happen. At 6 pm I was told it would surely happen by 8 pm. I did not receive any response from flipkart. When I called them at about 9:15 pm, after long hold and deliberation I am now told that it would happen by 9th February. No reason was assigned for the delay, no written confirmation. All this communication is with the customer care. They do not allow me to talk to senior officials nor give me a proper satisfactory response. The same product is avaiblenon their site at 2 days delivery. Why are they delaying my product. Please help me resolve this issue. Order ID OD[protected].
