Amazon — at last moment product showing undeliverable

Website:

www.amazon.in

I have placed order yesterday for my product and it was showing that this will deliver to your doorstep by saturday 8am-6pm and now the status was showing out for delivery and after 1 hour its showing that the product is undeliverable and its being returned to the seller.

Is it good that customer facing such huge issues due to their transportation services problem
And they dont get the product on their promised and desired date.

I wants my full money back first and wants to seek 10% compensation for this issues.
