I have received 3 phone calls today and now I am blocking it on my cell phone  I wish this idiots would just give up on doing this. I will be reporting  to verizon as well.  

I have recieved one call so far from this number.  As I do with all unknown numbers, i look it up to see who it is that is calling. When I read that it was Citi calling, I immediately checkes my balance on 2 of my 3 Citi cards (one is a company card with no balance) and neither have a due or past due amount. Once i confirmed the balance on both cards, i called the number back to see if it was an automated service - it was not. It was a normal phone ring for 2-3 rings ans when they answered, they just pressed buttons on their phone.

if they call back today, I will be requesting a name, number and extension, and of course company name.  

in dealing with Citi in the past, they have always 1) left a message and 2) called from a number that you can call back and get an automated service.

If it IS a debt collector, they have the wrong number.  I am thinking it is a scam, though

Phone rings 3 times and is gone. If you answer there is no one there except one time a message that says the mail box is full. They claim to be Citicorp but I don't believe it.

We have received more than a dozen calls from this number and they are asking for someone who has never lived here.  I called them back and told them of their error but the calls continue.

I have been receiving calls from this number, but have not answered because they don't identify themselves. A message was leftbsaying "If you are Laurie press #1 if not press #2.
Then I noticed ob my cell phone a second number with it and it turns out it's coming from my psycho exboyfriend's new girlfrienf. I'm reporting it to the police.
