They call 5-6 times a day. I won't answer it.
who are they and what do they want?

their no. is 516-800-0000

I have been receiving calls from 516-800-0000 for the past week, more than five.  I asked if I could have a number to call THEM back and the number they gave me was 800-360-3683, "Hottest  Talk Line For Ladies".   I have reported to FCC and placed my number on Do Not Call Registry.

I bought a new phone and i can block any number i want..it rings 1 quick 1/2 ring and then it goes quite...i blocked my cell number and tried it to see what it does and quick ring then it plays busy sound..best damn phone i ever bought..i get a lot of these numbers and block them all..lmoa..Panasonic KX-TG4741

I continue to get calls from this number at 2-3 per week. The few times we picked up, it was an obvious scam called claiming to be from Microsoft asking us for personal info, These calls need to stop.
