Same as below, did not answer and will report them to US and Florida lists.

Called my mobile number which is on the Do Not Call (DNC) list. Heard a beep, then static, then electronic noise (thought it might be a Fax machine), but no it was some type of prerecorded message in Spanish using a male voice. I listened for 2 seconds and hung up. I then marked the call as Spam on my mobile and placed it on the blocked list. Future calls (if any) from this number will be automatically intercepted by my call blocking app and disconnected and not routed to voicemail. So much for compliance with the DNC list!

This number has called me for days on end with no message or clue as to wtf they are or what business they need with me I've called back only to get an out of order phone line so I put them on my blocked list bc it's annoying

Got a call this AM, silenced it and they immediately called back. No VM. Tried phoning it back and got "call cannot be completed as dialed, please check the number and try again" type of message.

Same here, with that number, picked up and no one was there.

This number has been confirmed by Mr Number as not being a valid number. It was spoofed on the caller ID (illegal).  They're already crooks - reporting them to the FTC & FCC may help, but doubtful.  Best bet is to block the number.

Received two calls on my cell from this number today.  No message was left.  I tried to call that number from two different phones but it will not even go through. First, I hit the callback button on my cell and got "This number cannot be completed as dialed."  I tried again from a different number and get a text message saying, "At 10:17 AM (786) 555-8766 was not available for a phone call."  Peoplefinders.com Reverse lookup says it is coming from a cell phone, Owner name available for $2 (I'm not paying for it), carrier Omnipoint Miami E License LLC, location Miami, FL. My phone is registered on the "no call" list.  That used to mean something, but not anymore!

I missed call from this number and when I called back it said the number you have dialed is not valid.

Received two calls 25 minutes ago and they left no message.  When you call the number, it answers as Windstream, and asks you what city and state.

Got a call from 786-555-8766. They left no voice mail. My phone number is on the DNC list.
