I received the same message as a text to my cell number on the same day as Richard and like him I have no accounts with Compass Bank. Beware of this scam. His advice is excellent.

(Please Call CompassBank HelpDesk@682-227-8727) Your attention is required. Accnt Might Be At Risk.
This is obvious a SCAM as I do not have an account with CompassBank.

Never call them back and Never answer their calls and text messages. It's best to Never Answer A Call from a number you are not familiar.  If in doubt, go online and check them out first.

I will be filing a complaint with the Federal Communications Commission.  So should everyone, that is the only effective way to stop these people.  Go to: www.fcc.gov and file your complaint.
