Completely support the idea of going after the card company if the company you're buying services from has misrepresented and/or not supplied said services - see https://www.which.co.uk/consumer-rights/advice/can-i-claim-on-my-credit-card-when-something-goes-wrong
But is "theft of services" actually a thing in this context? I've not heard of it, and a brief Google suggests it is a term in use in the US, but applies to cases where someone forceably obtains services without paying for them, not where payment has been taken and service is not provided. Also from a legal perspective theft refers to a crime, but this would - like it or not - presumably be a civil matter under contract law.
It might be easier/more fun to use RICO if you think you can make out the case that Oracle is an organised criminal enterprise :)
