Amazon India — Order#[protected]

I have ordered one product from amazon india with Order#[protected] for which is in prepaid state, the delivery executive which was supposed to deliver the order within office hours called me beyond 9am -9 pm window however after unavailability he cancelled the order, i am not satisfied with the service which amazon is giving now a days, also for my previous order company has taken almost 2 months to credit my refund. Please look into.
