I have been getting tons of calls from this number.  We see it on tv and don't recognize, so don't answer.  Once the machine stops, all we hear on message is "21" and hangup.  Will now block number.  Helpfull to see what others are saying.

Started getting calls from this number Tuesday, Dec. 1, 2015, several times each day since, but today, 12/3/15 they called at 6:22 in the morning. Thanks to everyone's notes about this number, too bad this stuff still continues. Company name doesn't show up on my caller ID, it just says New York

Called saying their name was Dave and that they were calling from tech support about my laptop, to which I told him I don't have any issues with my computer and I hung up. He called several times after but I did not pick up and I added his number to the reject list!

Also received call from this guy. Asked him who he was and he said he was from my service provider but refused to say who they were.
Clearly a scam. Why are the authorities not taking action.

I got a call from this number like I do every freaking day and I told them to stop calling me and hung up then they called right back and I answered the phone with a rude "what?!??" And he said [***] you and hung up on me
