I got a call three times today from this number, twice while I was at work and once while I was at home. I didn't answer as I don't answer numbers I don't know. But reading these comments I'm pretty sure someone would try to scam me. Good thing I don't answer numbers I don't know.

A woman from this number called here yesterday.  She could barely speak English. She asked for someone who was not here at that time.  I said person was not here but could I take a message.  She slammed the phone down in my ear.  Will NEVER answer a call from this number again!

This is the Collections Department of "Citi First" which is part of CITIGROUP. They do the collections for many different 'CREDIT CARD" COMPANIES.

By the way, they also "service" other credit cards for multiple companies. So Citi will call you since they are servicing (managing) the banks/finance companies credit cards.

This is Citi 1st which is the Collections Department owned by "CITIGROUP."  If you have a delinquent credit card, then they are the ones who are calling you about 5-6 times per day.  Sometimes, they leave a message; sometimes they don't.

This phone called my unlisted cell phone number repeatedly today - April 17th. No one at the end of the phone, you just get a hang-up. very irriating.

Try answering the phone. It's GE Money Bank trying to collect on a late credit card payment. They handle Cjevron/Texaco cards as well.

Calls constantly from MO. Claim to be Citi. I don't have a Citi account.

They call every hour

keeps calling and not leaving meassage. all hours of the day. no name on caller id.

Waited on hold but they hung up on their end. Obviously not a real business

Called twice 24 Dec 2012 by 10 AM and did not talk.  
Is this a FCC or Police Problem?

I have had the same issue with these dirtbags. I do not have have any credit cards so I know it isn't the issue. It doesn't matter if you answer it, let it go to voicemail... what ever . They call like clock work 4 times a day.

What type of legal, legitimate company calls multiple times and hangs up without leaving a message?

Guess I'll never know.

they keep calling and its always the same woman. they refuse to give a name or any info about them except they are from citibank and demand i give them personal information or they'll freeze my accts. i don't have any citibank accts.

Just calls but no message is ever left.

Six calls in the past two days.  Caller ID says "Citi" and the number.  They don't leave a message.

Have received numerous calls from this number, no message left.  Have reported this to the do not call site.

Calls at least 3 times per day, sometimes before 8 a.m. Caller ID only says Missouri and the number. They sometimes will call up until 9 p.m. and sometimes within a half-hour of the first call. Jerks.

I constantly receive phone calls from this number wanting my name, credit account numbers etc...on my CELL phone.

I too received a call from these people telling me the account was in arrears.  I knew better because both accounts through Citi Bank were paid up, and had cleared the bank.  The girl said she wasn't showing that, and needed me to veryify the bank routing number and account number.  I said there was not need, I knew the payments had cleared the bank, we were not behind, and there would be no reason for her to call me back, then I added the number to my call block program.  There are so many scammers out there.  Never make a payment over the phone if they call you.

and when they called today it was a woman who identified herself as "renee" and refused to give a last name or employee number. She gave this number as her direct line: 877-483-9183 x 22670.

guess what? 877-483-9183 is also associated with a phishing scam. again - someone pretending to be from citibank client services.

If you're bored and this caller has been bothering you try calling this person every 2 hours and leaving no message and then when they do answer ask them for their bank account number!

This is a phishing scam. I got a call from this number every few hours with caller ID "Missouri" - when i finally answered it after several days caller said he was from Citibank and did I know I was 12 days late on my account ending in xxxx. I said OK, I'll pay through Citibank not through you and started to hang up and he said i could have my late fee reduced if I paid on the phone. That should have been a flag right there. At that moment I got a phone call so I asked the guy to call back. He said he was going on his break (... whoa am I stupid) and that he would call back.

He actually did and I was stupid enough to verify my address (he had that anyway). He asked for the password on my account and I said "huh?" He said "probably your mother's maiden name." I was stupid enough to tell him and he said "That's it." He also asked for the last four of my social (I can't believe I was such an idiot) and I told him that.

Then he asked if i would pay by debit card or check and when I said check he wanted my checking account number starting with routing number. at least I wasn't stupid enough to give him that. I told him I didn't feel comfortable paying that way because he had called me and not vice versa. He launched into a litany of what he knew (the last four digits of my account number, the date and amount of my last payment ...  and interestingly when I asked him for more info ... he kept saying he didn't have a clear view into the account, couldn't give me that info ... but hold on ... and then changed the subject).

Anyway gave me an 877 number and a six-digit extension and his name "Wellbert" I looked up the number and it was variously associated with debt collection and a Citibank phishing scam. Also looked up Wellbert and it is the name of an insurance? company in Missouri. Unfortunately can't find the 877 number now. I did think the six-digit extension was strange.

Then I went into my actual Citibank bank account and saw that I'm current on all accounts.

This number keeps calling every two hours or so, leaves no messages and if I am home to answer there is no one there, so I'm figuring it is a telemarketing company.  One previous post said this was CITI Client Services. I don't have any CITI acocunts and certainly none in arrears  so I don't want thier calls or business.

This is CITI client services.

Caller does not leave any message, calls every day seven days a week since the beginning of July
