8778188319

Same message left on my voice mail. Except the first part of the message was cut off so no co. was given.  I do not have MC anyway.
I never answer calls from 800 nor do I return them. Just to be safe, rather than be sorry.
Looks like AZ is a target.

I got the same message. It has to be a fishing scam.

I got the same call in AZ
I do not have a credit card with them.

talked to mastercard, gave them the phone number, it is a fraudulent site.  They say they will look into it, hope so.

Scam, Scam, Scam!  I got a call from this number 20 min after I had used my barclay MC out of town.  It is normal for them to contact me when there is a question on my usage.  This time it was automated and asked me to enter my # and I did, then it said it was incorrect and to try again, so I did, then it said sorry and disconnect me.  I immediately called my cc company, barclay, and they said they never called and it was a scam.  I am usually very cautious and amazed I fell for this.  Timing got me on this, please no one fall for this.

Received a call from 877-818-8319 saying something about a hold being placed on my barcley master card, I do  not HAVE a master card of any type

We have an AZ cell but are not there. Got the call at 11:20 pm didn't have good reception and don't associate credit with the # so figured it wasn't legit.

They really must be targeting AZ. They called me 2x.

Got the same message as others described, fraud department from Barclay's. Didn't call back the number they left as I don't have a Barclay's card and my credit monitoring showed no new cards opened in my name.  I'm in Arizona with a 602 area code/cell so they are definitely targeting this area.

Just received a call from 877-818-8319, advising us we had credit card fraud on a Barclay Card.  When called number back advised the number had been disconnected.  

This is definitely credit card phishing. When you call back they the first thing the auto answer asks for is your credit card #. We don't even have that card but they scare you into thinking fraud happened on your account and it's been shut down.  The call back number varies our call back was 866-467-4704.

I got the same automated message after I made an international purchase, called the number back, and stupidly entered in the requested info to "validate" my card.
A few days later, MC legitately did call me, and I had over $9000 of fraudulent charges on my account!
I'm also in AZ.
