Any cloud provider accepting prepaid?

I've been trying to create a test account with AWS and Google and they don't accept prepaid cards or paypal (Amazon does not even accept their own card!). I don't feel very well tying up my credit card on a test account (a lot can go wrong and I'd like to have the peace of mind that in worst case my prepaid is drained and that's that). Do you know any provider that accepts prepaids? (Note: I'm mostly interested in testing out kubernetes deployments). Thanks
