How come they are so unlucky? My case was OCBC personnel did call me my cancelled credit card got illegal transaction. At that time, I still pondering, cancelled card can still make transaction, is she a scammer? She also told me the bank will handle it. I still thought she was a scammer. I did an authentication with OCBC again after I have finished my call with her. Indeed, she was working in OCBC. I must give thumb up for OCBC for my case.
During my conversion with her, I did ask her how come cancelled card can still make credit card transaction, I remembered she said still can.

Now, I understand how come I cannot access my OCBC app as well online OCBC website. They are trying to protect me from scammers.  
Thank you, OCBC!
