877-372-3495

The message said it's "Fraud Detection Center". Then after a while they said that they are experiencing longer then usual wait time and to call 877-372-3495 to speak with a representative. I did call 877-372-3495 but again was put on hold.

The same thing happened to me, but when I called the second number a male voice came on and said "please hold while we trace your call....... thank you, your call has been traced."  Then, after a couple of seconds, it hung up.  Thinking it was some kind of error, I tried again and the same thing happened.

Got an automated call at work saying they were my bank and did I charge
A HUGE AMOUNT on my debit card- couldn't get the whole thing.  Said press
2 for no- which I did and rec'd recordings cust. reps were busy and to call
this number. Called, click, dead line.  Called bank- NO SUCH THING!  Called
few times....A live body said "Customer Fraud Calling Center" (didn't understand the name) and another time it was "Card Processing Center" (again
didn't get the name). My bank said they would personally call if there was
a problem.  Wonder what would have happened if I actually talked to someone
don't use my debit card AT ALL on line.  TELL YOUR BANK IF THIS HAPPENS!

Okay this is  my second time receiving a call like this.  The first time it appeared to be valid.  But this time it was for the old card that i called my bank and changed.  They said  maybe someone got a hold of the old card and tried to make a charge and to call my bank in the morning for a new card.  But that was an old card - which i changed.  Strange.  They say call your bank and say you've been contacted by the fraud alert department.  When i did that last time i just had my bank issue me a new card.  How do we know if this is fake?

I received 2 calls this morning from 1-866-750-9107 Fraud Detection. I called it gave them the 6 digit code they told me to punch in, then they ask for your zip code. I was then told due to high call volume, to call back.
I did see a charge of $30.00 from a TSP219 on my bank statement. I have no idea what the hell it was, but
best thing to do is report it to you bank and they will issue a new card.

Yep me too. I did call bank. Got new cards issued and changed all passwords.
Thanks L for the heads up

they just charged to my debit card ($49.95 (then the word 'pending' appeared after charged.  they have a website that is very familiar to the USPS site.  I went there to do a change of address.  so I guess they got me.  but now the charge is not on my online bank like it was earlier today.  I am just calling to cancel card.  sad.  this was a new card...they will answer to the Almighty one day and sooner than that for messing with God's children.  Peace and prayer for all...

Who are "they"? You say their website is "very familiar (I think you mean similar) to the USPS site" so you must have some idea of their identity.

These are scammers.A popular came on my computer and your computer is possibly  hacked. Call Microsoft at the 877 number above. Person said I was a victim of ID THEFT,sent a message to my computer asked me to accept,began to run something on my computer, asked me to go to my bank and see if I can access my bank account from the computer. Said he would dial the banks fraud debt and I needed to explain .Person came on the line said they take direction from the federal reserve and that I need to move money from saving to checking. No mention of closing my card down, but move money to another acct. Didn't  sound right. I shut my computer down and hung up. Called my local bank. HACKERS/SCAMMERS! Block the numbers.. Please beware.

I think you mean a Pop-up, not a "popular".
Your computer was not "hacked", those things get installed by sites you visit while web browsing or by downloading files from malicious pages.  You can find a number of ways to get rid of those Pop-up ads by doing a web search.
