Robocall from "Barclaycard fraud department" left voicemail saying a hold had been placed on the card due to suspicious activity. Asks for cardholder to stay on the line to verify activity or call them back at the same number. Calling back you get a "not in service" message.

This number seems to be a proxy of some sort; they're trying to directly reach people willing to enter card numbers because they are caught off guard and surprised/concerned.

Beware!!! ALWAYS call your card's customer service number (listed on your statements) first if you get something like this!!! Even if it is them, they will never fault you for verifying via their main number! KEEP CALM AND VERIFY. :)
