I ordered an item and selected one day delivery option as i m a prime customer i was not charged for it, however you people changed it to two day delivery. And today i got a message that the product is out for delivery and i called the delivery person several times to confirm that to deliver it before 4pm, and he agreed for that. However it wasn't delivered. And when i called customer care they denied to help and said that they cannot call delivery boy. I m really frustrated and i want to cancel my prime membership and i want the refund for the same
