AMAZON AGREES THEIR SERVICE IS TERRIBLE

I recently purchased a Gizzu power bank. The shipment was delayed according to the details on my profile, so I was just waiting patiently. Suddenly today the money appeared back in my account with no notification. Amazon Customer Service sounded unsurprised and not terribly interested. They even agreed their service was awful. Apparently the supplying company cancelled the order. I was supposedly notified by email, except the email lingers in their system because they don't have my email address! Meanwhile my profile suddenly says I haven't placed an order in the last 3 months. Really bad and don't-care-at-all service. Wish I could give them a zero rating.
