Never never never ever call these ppl back. Especially if they do not leave a message. It is another form of a scam going on where they charge you whatever they want when you call them back. 5109397010 This number keeps coming up on my cell. Today I answered it. Some spammers offered consolidation of credit card debt. BS. Never EVER call back phone #'s on your caller ID. Blocked the number and if they don't leave a message they must not want to talk to me very bad.
