Amazon changing the order status

I just had a chat with a customer rep on Amazon and something weird happened.

My rift order was in preparing for shipment few minutes ago, and I was charged for the order yesterday.

After a long chat the customer rep told me that the charge on the card was cancelled and suddenly now my order status says "not yet shipped"

This happened during the and I feel that the customer rep manually changed the status. Also, I can see a pending cancellation of payment magically appearing after my chat with the customer rep. He told me that it was done at 2:50PM today, but it happened few minutes ago.

Honestly, I woundn't have cared if he had told me that the item had been delayed and I can expect it by my scheduled delivery date.but changing status and rolling back payment is just wierd.
