Who called from 5154602739

No answer after I identified myself as I do when at work (hospital IT tech), dead silence then the call ended. Most likely some telemarketer.

Called 2 times within a short period of time.  They left no message.  I blocked them.

My 3rd or 4th call I took the call and asked where he was located...says the company name is Visa and Mastercard Services, Orlando FLORIDA. I asked for their mailing address, he hung up.  The number came in as Iowa.  I am positively sure it is a scam. I re dialed the number and a recording says it is not a working number.  Filed a complaint as my number is on the Do Not Call list.

Called and I answered with a hello, and it said that was an invalid extension. Then they hung up

Credit card scam
