I had something similar. One time I got a phone call from a "Scam Likely" and decided to answer it. And it was an automated message from my bank asking if some purchases in another state were real or fraudulent. At this point I began to second guess if it was a scam or not, but had to assume it still was. I ended up logging into my account and seeing the same fraudulent purchases that it listed over the phone. So I called the number on my card and had it all settled. I found it weird that the original call was a false positive though.
