Flipkart — Order cancelled by seller order id od[protected]

Address:

803101

I have bought the deluxe collection of paulo coehlo's books for rs 321. But they cancelled the order with a badly auto-generated apology message. There happened to be an issue with address and the courier company cancelled it. Also at the time when i was swiping the address of new delhi's with bihar's; their executive could have told me. So i raised a complaint regarding this and they asked me to place a new order with the current price tag of rs. 1724. Also when i reasoned them with the fact that my friend is also getting the same order from the same seller for the same pincode then they said that the seller didn't had the books at time when i placed the order then how came i able to place the order. I don't know about technalities and neither i want to fall into those... So just like to say if i am not wrong here please take some concrete steps regarding this
