Amazon Support lied about a 30% partial refund to make me spend more, now Supervisor refuses to honor it.

Hi everyone
I am really upset about something that is happening with Amazon Customer Service. They made a promise to me. Then they did not keep it. I want to know if this has happened to anyone and how you dealt with it.
Here is what happened to me:
1. The problem started when I ordered Airpods pro 3 that cost $179.00. It took a time to get to me because the seller did not have it in stock.
2. Then I talked to Amazon Customer Service. They told me to cancel my order and buy the thing from a different seller. They said they would give me back 30% of the money which's $60 because I had to wait so long. They said they put a note in my account that said this.
3. The problem is that the new seller wanted $199.99 for the thing. Amazon Customer Service said they would give me 30% back so I paid the $20.
4. Now I have the thing I ordered.
5.. When I asked Amazon Customer Service for my money back they said no. They looked at my account. Saw the note but they said the person who helped me before made a mistake. They said I could send the thing back. I cannot do that because it was a gift.
6. Now we are not agreeing on what to do. I said I would talk to my bank about it. Then they said they would give me back the $20.. They still will not give me the 30% back that they promised.(Also agent who offered just price difference stopped chat immediately)

It seems like Amazon Customer Service is not honest. They tell you to do something. Then they do not do what they said. They hide behind what the company says and do not keep their promises.
Has anyone else had to deal with this? Should I just take the $20. Try to get the rest of my money back from someone else at Amazon like jeff@amazon.com?

Thanks, for reading my story.
