We received a call, well, a voice message, on our system from over the weekend. The message seemed automated, but left the number for us to call back about "our accout number" and it gave an account number which matched nothing we have.
Be WARNED - if you RECEIVE calls asking for information about your accounts, DO NOT GIVE IT OUT - they HAVE the information if they are your true account carriers. If they have it, they need to verify it with you by giving you the information and you confirming it, not you giving it to them and them "confirming it".
