May be a phishing scam. I am getting swarmed with scam and phishing phone calls. They will not say whom they are. They know whom you are when you try to call. I also got a automatic call directing me to go to customerservicenow.com to stop telemarketing calls. When I researched this web address it showed this is a phishing scam allowing them to access your entire email contacts. They then would spam your contacts under your email address allowing them to seal more data from your contacts. I am also receiving calls encouraging you to press one to be removed from telemarketing, but you just get more calls.
