Ya, this same thing just happened to me today. Had so customers emailing me wanting to know why they received a refund. I go to investigate. My account no longer exists. I received nothing from google explaining be why. I have never had a bad order, refund request, email complaining about a product or service, etc.
I had only made 4 sales with the account, i received payment for 2 no problem. A few weeks later I had another 2 sales, and before they posted the funds, poof, I and the money no longer exist anymore.
I guess the internet's trusted companion can only be trusted for services not involving profitability.
