The number 1-412-223-4843 is a telemarketing company advising you that you've won an amazing vacation.They say that you or someone in your family has visited one of their sites on the internet. Just a bogus hook and reel strategy to get your money. You can answer and prompt to operator and request to be put on the do not call list. Hope this helps
They call me at least 5 times a day. I do not answer unknown numbers, if it is important then leave a message but like I said they call me like 5 times a day so I feel harassed.
