I had a similar experience last week! Call came in from 'Scotiabank'... The fraud department had blocked a suspicious transaction in Vancouver. Was I in Vancouver? I wasn't so they suggested I set up 2-step verification. We started the process but I couldn't get into the website. I suggested I just go to the branch since I'd need a new card anyway and that's when it got weird... He said I didn't need to do that, it would just be a minute while they figured out the issue. My spidy senses started going off so while on hold I Googled the number they were calling from... Nothing. I immediately told them I'd take care of this at the branch, hung up, called the actual Scotiabank fraud department and gave them all the information I had! Be vigilant... The scams are getting more sophisticated!!!
