Pretending to be RBC.

I got a text message from this number saying I need to confirm my identity for RBC

I got a text indicating it was from our RBX and that my account had on usual  activity and to call them immediately otherwise my account could be closed.  I did not call but called the RBC number on the back of my card to confirm. They said that they had not texted  and that my account was fine.  They said not to contact them.
