They call 6-7 times a day about credit card bill but never give the name of the company they don't let u talk they leave message about legal documents but keep putting you on hold the minute I told them I know it's a scam they hung up only to call back 15 min later

It appears that this is a debt collector scam and tax fraud scam.  A report on alpinecommunitynetwork.com makes the compelling point.  Here is the link.  Scroll down to the second post by LR on March 3, 2015.  It's clear these are scammers.  Block the number.

Note that she was given a number to call which is supposedly a lawyer.  She then learned that the lawyer doesn't exist. The number she was told to call is also listed on 800notes;  here's the link:

Clearly this is a SCAM.  Don't answer, ignore 'em.  BLOCK THE CALL.

Is this number legit?
