Attemted to get me to call them using false information. stating that my card starting with 4852 had been deactivated

these people keep sending test messages telling me that my debit card has been frozen. please call this number to take care of your account. i call to tell them where to go. it's an automated system and they want me to enter my card number and pin number. this has been going on for over a year. i contacted the actual credit union west and they said they can't do anything about it, but they do acknowledge the scam. i have never used them as a bank and never would. why is it just their bank? how did they get my phone number? this can't be right. can't someone do something?
