So, I have now received a call twice from this 972-541-4000 number.  Yesterday I was awoken at 6:35 a.m. and today at 7:55 a.m.  I know this is a Texas number as it reads on my caller ID.  I also know that I live in Arizona.  Yesterday, when I called the number back I got  this message "We are sorry you have reached a number that has been disconnected or is no longer in service.  If you feel you have reached this recording in error please check the number or try your call again".  This is a recording".  Today when I answered, I only heard static and loud popping sounds.  I tried to call back and received the same message as yesterday.  Usually I do not answer or call back.  Guess now I am going to hear from this number every morning until I die because someone does not care about what time it is where I live.  

Got a call on my cell phone and a blank voicemail. I did not call back. No idea who it is. Came up as Irving,TX for location.

it's CITI.  I used to work for one of their call centers and after I quit they tried to claim that they over paid me.
Yeah, that's not going to work out too well for them.

They call and don't ever leave a message.

called MY line and asked to speak to one of my associates and my supervisor, who the hell is this guy???

I received a call from this number and have no idea who it would be. I don't know anyone or do any business in TX. Also, collection calls are not something we normally receive in this house. So, I am not sure who they are or what they wan. I tried to answer and nothing was said. Thanks for waking my 16 month old up from his nap for nothing!

no answer
