I think you'd be a lot less impressed if you'd received any packages through their fulfillment services. Literally every single driver I've had has lied about attempting a delivery, usually multiple times, then flat out lied and said the package was delivered. The package will then show up 2-3 days later, defeating the purpose of paying for prime or faster shipping.
Customer support for these issues is kafkaesque.
"Hi I have not received my package which says it was delivered at a time when I was home"
"Let me check the tracking, sir it shows that you have received the package"
"I have not, no delivery was attempted"
"Yes you are right you will receive your package shortly"
