This number has called my house every 15 minutes today.

These jerks are persistent.  Calling every hour or so since about 2:00PM.  Caller ID says "Voice Network I."  I'm not answering.

This number has called our house seven times!!  We have caller ID and never answer it, and they keep calling!   it is really annoying!

Got two call tonight from 248-270-3480. Did not answer phone. No meddage was left.

Called my wireless number, left no message.

They tried 3 times but I never answered because of caller Id showed it as Voice Network I and I knew it was someone trying to sell or something similar.

They call but don't leave message and then call several more times.  This last time I answered and waited.  They hung up.

Caller ID is the phone number; I never answer, and the fool keeps calling, and of course they never leave a message.
Tonight at 7;53 and 8:09. Persistent b*****ds aren't they. Call is from Auburn Hills, MI and that is near the Palace, where the Pistons play their games for those getting this call # and don't live in MI. My guess it is a cell phone they use.

QUIT CALLING! THREE TIMES WITHIN A TWO HOUR PERIOD..1-248-270-3480

this  number called several times yesterday and one of the calls was well after 9 pm i did not answer because i did not know the number . i counted a total of 10 calls just for yesterday on my caller id

They called me twice tonight, the 2nd time was after 9:00pm.  I dont answer the phone and they dont leave a message.

They called me twice tonight, the 2nd call was after 9:00pm.  I dont answer the phone and they dont leave a message.

Received three calls within 10 minutes this evening (Oct. 27, 2013). Left voicemails identifying the caller as Samantha Artley, candidate for East Lansing (MI) City Council. I am not a registered voter in East Lansing. Another posting here identifies the caller as a political pollster, but on another list, the number is listed as Farmington Hills (MI) Locksmith.

Someone from this number keeps calling me, three times tonight alone.....no one on the other end.
Pretty irritating is right!!

Two separate calls.............no message............caller ID showed 2 different "names".  IRRITATING!!!!!!!!!!!!!!!!!!!!!!!

We received five phone calls from this number yesterday, August 25, 2013 (a Sunday) between 6:24 and 7:30 p.m. The ID said "PRIVATE NAME," so we didn't answer it. No messages were left.

This number calls and no one is there.  It just keeps up.  There has to be a stop to these unwanted calls.

I keep getting repeated calls from this phone number.  Sometimes as many as 8 in an evening and always within a few minutes of each other if I don't answer.  I don't know what organization is calling, but when it answers (which is only 1/2 the time) it is a political survey.  If I try to call the phone number back, I get a fast busy.  How do I make the calls stop?

Called numerous time.  Finally recorded message for political survey.  Slammer?  Dont answer

This number has called me 3 times now.  Once at 6:06pm, next at 6:46pm and then at 6:56pm.  I hate these calls from scammers!

I know they are NOT legit calls because only real and legit businesses follow the "do not call" list.  They must be a boiler room type of scam.  I am ready for their next call, I will play them this :)

Called twice in 15 minutes. Left no message!  Sick of the junk calls!

Just got 4 calls from them within 40 minutes.  Caller ID said Voice Network.  No message - didn't answer

This number called me four times in 20 minutes! No person / no recording....thin air!! How do I make it stop??

Called at 8:29pm on Monday night.  Called ID said "Voice Network I."  Have already filed a complaint with donotcall.gov

I got a call from 248 270-3480, but didn't recognize the number, so I didn't answer it.  They left a minute or two long "message" that was nothing but dead air.  The caller ID said "Voice Network I".

When I answered, nobody replied.  
I'm going to report them on the Do-not-call site.

This number called me 3 times this evening. Didn't recognize number, so I didn't answer. They didn't leave message. Must not have been important!

calling every ten minutes  wont leave message...annoying!

This number has already called five times today and each time said nothing. They called three times yesterday.

I got a call from Voice Network I - no idea who it is.

The "DO NOT CALL" federal blacklist is a load of junk. It never helps.
