Amazon review: Unable to cancel air frier 5 minutes after purchase!

I have a Prime membership and an Amazon Fresh account with Amazon since the beginning of this year. I have used them for everything because I am elderly and don't drive so I need a delivery service and Amazon started out doing well and their customer service was good until yesterday

I placed an order yesterday of 3 grocery items and an Air Frier when I noticed that I was being charged $2.99 for delivery and items were sectioned out separately with the fryer taking 3 days for delivery while the grocery items were scheduled for the next day. Usually I dond't get charged until the items are shipped but I noticed while I was on the phone with their Customer Service to find out why I was being charged a delivery fee, the Air Friers was being paid already with my Apple Pay. (Red Flag) I told the rep, I want to cancel the order and told her how surprised I was they were processing my payment as I was on the phone with her. Told her I wanted to cancel the order and get my money back to which she said, she could not do that. I told her I would call Apple Apay and stop the payment! Called Apple Pay and they said I had to wait 15 days to dipute it, eventhough I told them what had happened. I cancelled the Air Frier through the App or so I thought, until I checked again in the evening of the same afternoon I placed the order and saw the email saying they could not cancel order because it was already in shipping! WHAT? Inmediately called Amazon again and spoke to another pushy, heavy accent inconsiderate customer service rep who told me she would send an email to the warehouse so they can cancel it there, which I had nevere heard of before but I went along with it for now. Woke up this morning to another email saying they could not cancel my order, and Friday is the delivery date, still 2 full days left which according to Prime memebership it should be delivered withing 48 hours but their delivery date is 72 hours and not cancellation possible once you place the order and 30 minutes have passed! That is what I was told this morning after I called a 3rd time to cancel the order. All I have to say is that Amazon must be going bankrupt when they are this difficult to cancel an order just placed and get their money within 5 minutes of the or placement. Their customer service is just as bad, people working in a call center in another country all yelling and talking in the background like animals waiting to be fed. Speaking to a supervisor is as tough as asking for the Jeff Bezos! I am disgusted by how low they have become and how little they care about their so calle
PRIME CUSTOMERS!
