This is a scam. They keep calling and I was ignoring their calls but answered and they promptly hang up. I called the number directly and a computer voice answers saying "Hello. If you would like to be placed on a do not call list dial 1." This is where they want you to put in your number, which then triggers their computer system that a live person is actually at this number and the call volume usually increases. Other than dialing option 1 to "remove your number from their call list" no other number or symbol directs your call to anyone or anywhere else and it will hang up on you.
