This was a legit call. They caught and blocked some fake charges and put the card on hold. I checked online and confirmed that the charges they mentioned were not made by me. They said they are employed by the issuer of my card and when asked were able to confirm the name for me. They cancelled the old card and requested a replacement on the spot.
I got a call from this phone number today, They wanted me to contact them concerning my credit union's fraud department and credit card activity. I checked with the credit union and they had no problems with my account so I'll be disregarding this phone number.
My wife received a call from this number today. They left a message stating that they were calling on behalf her credit union card fraud security and requested that she return a call to 800-238-8604. She is going to contact here CU directly.
This is actually legitimate. I've placed two internet orders in as many days, the second was with a company overseas. Only a few minutes after making this second overseas purchase I got a call (which I did not answer) and then voice mail from this number (claiming to be with my CU, which it's technically not) stating that a fraud-hold had been placed on my debit card due to "unusual charges" and then instructed to call 1-800-889-5280 with a reference number they also provided. I was leery, so I googled the number and found this page. Then I called my CU. My CU confirmed that there was indeed a hold on my debit card and told me to call them back. Reassured by my CU, I called them back at the 800 number, they asked for my name and my reference number, then asked me to confirm the last four digits of my SS#, which I reluctantly did. They then asked if both charges (they gave me the correct vendor names and exact dollar amounts) were initiated by me or if they were fraudulent. I told them I that I had indeed made the charges. They said they would release the holds on the card and it would be usable again in just a few minutes. My advice, call your bank first, confirm the hold with them, and if it's legit, then call these guys back to get the hold released.
Yes, this is a real service. They called to let me know that some sly fraudster had placed a charge on my debit card, before it even posted to my online statement. They advised me to call my credit union and have my card deactivated.
Call back, as it may be time sensitive information about your accountl.
