For a lot of reasons, cloud providers will never tell you how they investigated or what they found out. Telling you only has downside - either they give away information about tools & techniques, or they leak PII of other customers, or you engage them in a protracted discussion which will suck time away from addressing other abuse complaints, etc. So you will never get detail. That doesn't mean that they didn't do anything, it just means that there is no upside for them to sharing details with you.
