I got a call from this number but the voicemail message is completely blank. There is several seconds of silence and then a hang up.

I JUST received a call from this number and googled it to see if it was a scam.  I received a phone calling stating "This is not a sales call..."  I hope I get them twice a day.

Too much time on their hands and not enough brains in their heads.

I tried to call this number back today and it tells me it has been disconnected.  Maybe they finally got the message?  We'll see.

Leaves a message from a woman's voice.

These whack jobs are calling me every day even though I'm on the do not call list but they still call, make the madness stop!

877-377-3099- i keep getting these annoying calls and leave no message

You tell 'em Sister!

I have had 4 go-arounds with this HARRASSMENT.  If I ignore the calls, the computer dials day after day after day and the same message is left:  something like "this is not a sales call, but is important and please dial the number 1-877-377-3099".  I've had my phone number for years, and I'm not "Rosibel" someone or other.  I've been LIED to 4 times that the phone calls will stop...and a few months later, they begin again.  I finally called for the 4th time yesterday to stop the 4th go-around, and for some reason, I was furious!  (Of course, I'm being sarcastic!)  How does this company get away with this?  I have been on the "Do Not Call" list for years, and yesterday was so mad I called the police.  If it happens again, I will call and call and call until I find some way to make sure it stops once and for all.  ENOUGH.

i get a phone call from them to. same lame messages.they give you a call back number,are very rude but i still cant get an answer as to what they want. i wonder if i could do something about them calling, like harassment?

Call the number back - 877-337-3099 and press 0 for a cust. service rep. and ask to be removed from the list. I have no idea what company this is, but it is a collections company. The only reason I know this, is because my ex-roomate was a real scumbag who never paid his credit card bills.

We are getting this any many others. We had switch service form ATT to Cable phones and it seems that they are come in more than ever.

The numbers that we would like to know about is:
800-900-1372 Penn Credit Corp.
866-478-8892 (Dont know)
877-337-3099 (Dont know)
888-337-3474 (Dont know)

Pretty much takes up the phone on weekends, we just sit around answer the phone to get a #%mn Recorded message or a dead line.

received call from 877-377-3099.  Recording said "Press number 1 for an  important message"  I did.  Lady came on the phone, couldn't get the name of the person she was calling.  I wouldn't give out a name. Asked to be taken off the calling list.  She got rude and said she didn't "have time to play games".  She finally hung up.

I set my cell phone to recognize this number and then set the ringer to "silent".  My cell doesn't bother me and neither does whoever it is that wants to bug me from that number.  They plain and simple....just don't matter anymore.  Too bad.  So sad.  Those poor b*****ds can call until HELL freezes over and they won't get an answer.

me, too, 877-337-3099. I never answer, they never leave a message.  Where is the profit for the caller in all this?

I receive to my work number about 3-4 calls a day from the same number stating the same message as above.

I JUST received a call from this number and googled it to see if it was a scam.  I received a phone calling stating "This is not a sales call..."  I hope I don't start receiving them daily.

SAme as many reported. No ID from caller and saying it is not a sales call. Called back one and got a very rude man. Asked them not to call but they have called again.

I answered the switchboard when they called my place of business.  I don't even know who (which employee) it's for.  I won't call them back.  
Who are these people?

same as a lot of the above, "hello, I'm calling with an important message. This is not a sales call..."

constantly calling.

Up to 6 calls a day to my Sprint cell # which I've only had for a month the calls started 2 days after I got the cell. They are recordings saying to call back they come from both 1-877-377-3099 and 1-877-337-3099. One of your postings from someone else who is getting these calls stated they come from
a collections agency of some type:
Denver Technological Center
10000 East Geddes Ave
Suite 100
Englewood, CO 80112
Toll Free (866)-488-4299

I keep getting calls from this number on my cell phone while I'm at work.  I refuse to answer these calls but I'm very upset that I'm getting them.  If a company can't leave a message as to why you should contact them with a persons name, I refuse to answer or return a call.  This is very annoying and I wish someone would make that company quit making senseless calls to just about anyone they please.

Very rude, annoying calls referencing something from over 10 years ago!

I haven't had my home number for longer than week and have received phone calls from this number everyday. I tried calling back and it send me to a local number and the poor gentleman did not understand what I was talking about. Finally I called and got through to some rude woman who laughed at me when I said I wanted to be taken off their call list. She said, "Honey, we don't have a call list."

This is not a sales call, please call 1-877-337-3099 (was a female voice and is now a male voice...April 20, 2007)...receiving these calls for 1+ month.

Silent caller or a woman's voice saying "This is not a sales call - please call this number ...."
