Call me once every week. Really annoying.
They won't speak until I speak first.

I am getting calls from 1-800-974-6340 at least 2-3 times a week and they are rude and insist that I am who they are looking for.  The person they are looking for has the same last name as me and that is it.  All they say is that they are from Viking. Someone needs to get controil over these people.

They are calling me about every hour and it is very annoying I don't know these people and all they say they are from Viking what is Viking I would like them to stop calling me.

This is a collection company. File a complaint with the FTC go to there wed site FTC.GOV.

Woke up with a missed call from them ... glad i didn't answer

This number calls about ten times a day...I hate it and don't want them to do this anymore. Help!!

Get called daily. They were short with me and hung up.. then kept calling. I have no debt, therefore no reason for a collection agency to call. Report filed with FTC.gov

Just add their number(s) as a new contact in your phone with a ring-tone of MUTE... you'll soon forget all about them!

Ok..so they just called while I was home.  I answered it and an automated message asked me to hold for an important message.  After about a minute, a woman came on the phone and asked for "Carl".  I told her there was no Carl at this number and she questioned me as to why she would have this number for "Carl Tatum".  I told her that we've had the number for 7 years and had no idea who Carl was.  She apologized and told me she'd remove our number from her database.  Ugh.

Over the past two weeks, I received numerous messages from Chris Thomas. Thanks for the info guys...I had no idea that Viking is a collection agency.  I'm not calling them back, as I'm confident I don't owe anyone money.  If they really need to get in touch with me, they can mail me a letter.  I'm NOT playing their game.

Did not answer but they left a message- saying they are from Viking and I need to return their call. No reason why. Thanks everyone for posting.

Multiple repeated calls with no message left until today from something called Viking.  I see from previous posts they are some kind of collection firm and since I don't owe anybody anything and my phone is on the do not call list, I'm pretty pissed

I get these calls also from the 800 number but they do not leave a message and when I answered it one time it was a message to call them back. Today they called with a different #952-944-7575, completed reverse check and here is their info:  Viking Collection Service Inc 7500 Office Ridge Cir, Ste 100 Eden Prairie, MN 55344-3783.

this number keeps calling me and every time I answer because I'm curious as to who it is, but every time I pick up they hang up on me. so finally I called back and they asaid they were called the Viking corporation, and they were looking for my mother but wouldn't tell me anything else and kept asking for my moms number. also said they needed to talk to her about a "small business matter" which makes no sense. absolutely annoying.

Got a call from a nasty person asking personal questions. I was like I will call you back. Hung up then try to call back and guess what! Its disconnected. Stay away from this fraudulent phone number.
