Stop calling

Answered the call to no response and an eventually hang-up.  Called back and got a very pleasant operator who looked up my number, gave me a name they were looking for who was clearly not me, and said she'd remove my number from their system.  We'll see how that goes.

This company is ridiuclous.  They are non stop even when you answer the phone and give them an answer as to when you can pay or if you can't.  I spoke to them 1/2/13 in the afternoon explained the situation told them when I would be able to pay they noted my account but yet they keep calling non stop from all different numbers..  There are notes in there system I confirmed it today when I answered yet again but they keep on calling.  Really ticks me off and there should be a law against how many times a day and week they can call trying to collect a debt..

Turn it in to who?

I get called by this number numerous times a day. A few times I did answer, they hung up. Just like someone else mentioned. I want the calls to stop. They call from about 8am to 9pm at night. It's very, very annoying. They never leave a message either.

My daughter just got a TracFone and there have been missed calls from this number.

this number calls non stop all day.

I also got a call from 412-927-4113, at 5:13 pm.  The caller left no message.

Calls 3 times in a row around 10, 2 & 6

Then repeat from another number the next day. 202-559-4758

Call me Business cell phone looking for a third party I don't owe them money.

ok, i've had ENOUGH of all of these out of state phone calls! and no letters in the mail proving that they own the debt?! it's time to fire up some c&d letters!

I ignored the call, Googled the number and read this information, then called back wondering what I was going to face. But they were very nice and helpful. A positive experience.

I've received several calls from this number. When I pick up they hang up.

They called on my private cell phone number and I am on every do not call list.

Call my cell again. Hell will bust wide open and u will meet Satan.

Just got a call from 1-412-927-4113. They did leave a message. They only call the cell phone. Next time they call I will answer the phone and they will think they have gotten a hold of SATAN. I work nights and I am in central timezone. So ring my phone again. Hell will bust wide open.

Collection's / a***olelickers.Can be safely disregarded

Large collection agency with offices all over the US.  They will call you several times a day and at night, all from different numbers and different states.

Got a call from this number. The caller left no message.

This number called today and the lady on the other end was very rude. I told her if this is a personal bussniess matter she needed to reach the person on her personal line. Told me I want to speak with your suprvisor. I told her speaking she hung up. I called the number back and was just as rude to them as they were me. I told them you call my office one more time and i will report you for harrsment. The man said he removed our number off the list. we will see if they call back

Pinnacle Financial is a debt collector.  They have many different numbers and they show up on my phone as calls from Florida, California, North Carolina, South Carolina, Texas...the list goes on.  I guess they think they are smarter than we are.  They are rude and sarcastic if you try to talk to them.  It doesn't matter if you are the person they are trying to reach or not, they still seem to enjoy demeaning you.  I have had enough of them abusing the privelege of calling my phone and plan to report them.

Someone continues call from this number (412) 927-4113.  I need it to stop.

Emily, it is illegal for them to call a minute after 9PM anyone's time.
Ie: I'm central time if they called me @ 9:01 PM my time that's illegal I can
turn it in.... I hope you did.

They keep calling, never leaving a message-then I called back and they said are you-------- and I said that I just got the telephone changed.  I will take you off the list.  Called again the same night around 9:30PM.  They call morning-afternoon and then again at night!  VERY ANNOYING! VERY STERN WHEN TALKING-SOMETIMES HARASSING.  Once said some financial Company
