This year some of my RIs became useless to me with a chunk of the 3-year term remaining, due to the EC2-Classic shutdown. (The instance types were a couple of generations old, and no longer available in the same availability zones in the VPC network.) Since understandably no one on the marketplace wanted to buy them, I asked AWS to credit me for the unused time on the RIs, with a promise that I'd spend the credit on new RIs on the latest generation hardware. They kept saying no -- RIs are a commitment, even if they become worthless due to their own mandates, apparently. I spent 40 days on a support ticket in which they'd go silent for a week at a time and then come back with an offer for a credit conditioned on me committing to buy way more RIs than I need. Finally they just bought my unused RIs from me on the marketplace at their full value. An acceptable outcome, but I should never have had to fight AWS for this credit.

No familiar with AWS. So you got Reserved Instance Credis that are only able to specific Instances, but the Instances were no longer available to “buy“.

If that, it is insane that you have to fight that they give you your money back.

You should talk to your account manager but for non ec2 services we have been successful with exchanges by explicitly asking for an exchange for a similar/larger amount.

We had to buy the new reservations first and would then could cancel the old ones
