Who called from 5162179256

Just rang my house phone.  I let the answer machine take the call.  No message was left.  Not important.
C.I.D. indicated support associa[tes].  Probably it's support for a scam or political survey???

Call received at 1:31 pm EDT Wednesday June 7 2017.  Lett no message. Upon call back from a blocked number, I got 'no operators are available to take your call'.

same above

Same here.  Caller ID says Cold Spring, NY.  Called just now (2:43) and yesterday at 2:25.  Robo-call.  Will report to FTC.

Telemarketer at best, scam artist at worst. They called several times today, but left no message. Woke me up with an 8:30 AM call. I cannot block my landline, I complain to the FCC, but the do not call list is less than no help.
