I answer a student help line at a small community college. I am obligated to answer all local calls forwarded to my phone. This isn't even my state. Checked some web sites like this one, glad I didn't answer.
No message left.Called them back and man answered "Card Services".He repeated this 4 0r 5 times and then hung up so I suppose I gave them just a least a liitle of their own tactics.
Called home phone at 8.40 am -- Phoenix number, which means it was either 6.40 or 5.40 am there (unless the AZ number was hijacked and being called from overseas or elsewhere). ID Said Triple V -- I called back using *67, and a recording said Agent number 999 not avaialbe, please leave a message --- then, "I'm sorry, this persons mailbox is full". .... OBVIOUS SCAM -- so NOW BLOCKED !
