Refund

I received a text msg supposedly from Telus saying 

our latest check resulted that you;ve been overcharged on past telus bills. to obtain a reimbursment, please reply Refund

It then takes me to A "telus"  log in page and lists financial institutions I can deposit my money at. Then I have to log into my bank acount... Is this for real? Not sure I want to log into my bank account
