This number is cross-referenced on this site with 201-374-8619. When I go to the website you provide, I find a phone number in the "contact us" section ("please contact us by dialing 866-950-6550"). The address at the bottom of the website's home page is different than the one you note -- this one is in Maryland Heights, MO 63146.

They called this morning at 8:43 a.m. and didn't leave a message. No doubt looking for people who had my phone number a couple of years ago.

Gets call from this number on my cell. Want them to stop.

I got a phone call from this number. I called it back and she didn't know who she was calling for. She let out an annoying sigh and says "ok, we'll take your name of the calling list"
Who are these people? And what would they want from me too?

877.335.9692 hangs up when I answer at work with the name of my state agency employer.

They call repeatedly but hang up before the machine answers. I don't know who it is but it's kind of dumb for a debt collector to call and not leave a message. Are they trying to collect a debt or just to harrass people?

Suite 302 - 4 W Red Oak Ln - White Plains, NY 10604   And of course, no phone number on their website: http://www.visionfinancialcorp.com/index.html   I don't have any late bills, I can only guess it's a call for the person who had my number before me.

Got a call today and when I called them back from another number the woman who answered said their name as Vision Financial and when I asked what kind of company they were she gave an exasperated sigh and hung up on me.  So, I called back and got a very rude woman on the other end.  She wanted the number they had called and said that they didn't call the number shown on their caller ID.  I said, "No, of course not, I just wanted to know who had called me."  She then asked for my phone number to see if they had the right number.  I told her no, I wanted to know who had called me and she said "Ma'am, what are you hiding?"  I promptly hung up on her.  I have no debts, and know of no reason they would be calling me.

Get a name and employee# if they have it.  Craft a basic Cease and Desist letter containing the number and your address.  Mail it certified.  If you get even one call or letter from this company you can sue them without the need for an attorney.

someone from Sierra Leasing...

Caller said it was from Sierra Leasing.

This number says it's "Vision Financial".  Debt collectors, almost certainly.
