Same as others. This is the latest spam caller. They call and look for either an answer or a voice mail. They then up date records to indicate your number is a valid phone number and sell those validated numbers to marketers. A validated phone number is worth more. If your phone has a block or auto reject function add this number to it. They can not tell if your number is valid or not since it will not go to voice mail if you do not answer.
It's a answering machine saying that I owe more than $10,000 in credit cards (uhh no I don't) and they can help. There is no option to opt out. I spoke to a rep and asked him nicely to remove my phone number, he HUNG UP ON ME!
