800-386-6624

I didn't call Citi back.  I went to their website and discovered that I have 17 fraudulent charges all from the same company all this morning.  Since the voicemail was left saying it was Citi calling to confirm some possible fraudulent activity.  I can only assume that it really was after looking at my account online.

received the following text message on my cell phone :citi cards fraud dept; did you attempt a charge at in the amount of $125.00 on 02/23 with card ending in 3744? yes,reply 1,no,reply 2,You may also call 8003866624 and enter case 5312541.

It was Citibank calling to determine whether a transaction was fraudulent.  Legitimate CitiCard telephone number.

I got a call and text from 800-386-6624 and was skeptical since that's a different number than the standard Citi fraud line. I called the number on the back of my Citi card and they confirmed that it was a legitimate call, and that the 800 number is a real Citi fraud number.

I have received over 50 calls with a variety of area codes and exchanges but all ending in 6624. Some include a name either personal or business.  Regardless, they are spam all referring to (if they leave a message) to getting lower interest rates.  Since the 1st 6 numbers are always different I can’t block them.  However with caller id at least I know not to answer them...

It is Citibank Fraud Dept. I received a text from Citibank asking me if I attempted a charge for $51 at Groseto Trading. It said to reply back in text with 1 for yes or 2 for no or call 8003866624 gave me a case #. I replied with "2" and then they called me.
