Repeated SMS to authorize "suspicious" transaction
A month ago I received an SMS asking me to approve a "suspicious" transaction. I did and received a confirmation SMS. A few hours later, I again was asked to approve this same transaction. After going through this process six times, I STOP's SMS service.
A week ago, I thought I'd give it another try. Sure enough, I triggered a "suspicious" transaction (different from the one a month before), and again I went through 3 authorizations (each one received a confirmations SMS) before I again STOP's SMS service.
What's up here? I can't confirm my phone if I'm getting endless confirmation requests... and also worrying that a transaction may be denied because I didn't reply to the 42nd SMS on the same transaction.
