bogus text messages regarding credit cards that have been frozen.

The text message references this number to call and that my credit card has been frozen. I know I don't have a credit card with the bank that was referenced so I never called. I did, however,  call my mobile service carrier who indicated that if I don't call the number I should be ok but I still have to pay for the text messages. That's not fair and for all I know it could be T-mobile themselves, especially since lot's of people are having this same problem.  They are the ones benefitting.
