He called me and didn't say anything I hung up in under 10 secs

Call - they do not leave a message - name comes up as, "Lower Tax" - reported this, too, to the DNC Registry.  Does it do any good?

They keep calling and never leave a message. My number is on the Do Not Call List but a few of these calls still get in.
I have no idea who they are.

This is a solicitation

Wrong, its not the government or a real collection agency calling you! its a total scam and these need reported to the real IRS:

Received an automated call about IRS Debt/Back Taxes and "new" Obama programs to wipe out or eliminate.

Obvious scam...the Feds want their money and will stop at nothing to get it.

You are basically paying a collection agency to come and get you.

Some recorded nonsense about tax penalty.  I hung up.  Called the number back from a land line and it said to press any key to get off their list.  

Keep getting phone calls from954-271-3292 since yesterday

does not leaver a message

Just received a call from this number, I cancelled the call but they did not leave a message. I blacklisted the number on phone.

I received a message from this phone number which indicated to press "1" to not receive any further calls but I believe this number monitors your calls which is illegal. If anyone knows where i can report this number for illegal monitoring of phone lines please advise. Not only is this number a thief but of illegal wire taping! Beware do not press "1".

I get calls from this shyster on a regular basis.  I have opened up an address entry on my phone for 'Thief Thief' which shows up on my phone when they call and I know right away, not to answer it.  Where is Paladin when we really need him?

keeps calling my number no message
