Who called from 3134343640

This # texted the following message, which leave a 2nd phone #:
"CSCU ALERT: Your CARD starting with 4626 has been DEACTIVATED.   Please call: 734-250-1848"

Got the same text today at 3pm. Don't know who or what this is, as I am not a member of CSCU and don't have a card from there.

the same text message text from 1-313-434-3640 but said to call 1-734-612-5784...  Iam glad i looked the number up before i called thank you now i feel better iam so happy i didnt call the number back its a big scam

I got the same text last night. I knew I didn't have any card with that beginning so I looked it up this morning. THANKS for the posts! It just confirmed what I had already suspected.
