Glad I found this too.  I've gotten two phone calls from this number today - the first one I was busy and didn't pick up but noticed it on my Caller ID which said "AVA"; the second time I did pick up.  I work with a lot of different people in the US so I assumed it could be one of them.  They started saying that it was in reference to my MasterCard account.  I said which one I have several...they mentioned a name that I have NEVER heard of before, and when I said I was unfamiliar with them, they said thank you and hung up.

I never heard anything about a gas card.

I absolutely hate and despise scammers.

Thanks for everyone who has posted comments on this.

I received the call from 201-257-4421 and ID shows POTS Phone NJ 2 times then same number came up as Hasbrouck He NJ a few times before.

Alyjough on yjr "Do Not Csll Registry" we have goyyrn 7-10 calls from 1 201-257-4421 Don"t know them so never answer . Still it's a pain just to see that same # over and over again Can nothing be done to stop this?

Just got off the phone with the FBI office in Newark.  This number will be added to the list of numbers to monitor shortly.  They suspect it's a trunk jump.  (Call is from overseas)

Number calls at all different times and it doesn't matter what day it is. National do not call registry as stated previously obviously does not work unless its an 800 number. This has become a pain in the [***].
