We are now getting calls from this certain number in Delaware every day. This is getting annoying. Even though I don't pick up the phone, it bothers me when I see this number on the Caller ID. I answered it once but there was no one on the other end, not even a fax machine! I know that our number is already in the National No Call Registry so I am puzzled as to why some Telemarketers are still calling. I found this website where you can search by phone numbers. Find Out Who Called You. Just enter the unknown number and you will get a full report for a fee. I read somewhere that you can report this to your state's Attorney General. Make a detailed list of the times and days that they called and turn that in. I hope this ends soon.
