i have received several calls from this number. Doesn't leave any message. Can not return call.

I tried calling it back and got a message from Verizon that the number has been changed, yet it just called me.  Strange.

this number is calling frequently cannot find who it is . have reported to fcc. any info please contact fcc. thank you

2 calls in past two days.  Call-back to this number produces silence.  Left a voicemail of silence-hang-up too. Annoying.
