BPI credit card no annual fee offer

Does anyone recognize this number? I received a call from someone claiming that my credit card account was eligible for a no-annual-fee card. She asked how much of my credit limit was still available. Is this a legitimate BPI call, or could it be a scam? She didn’t ask for any other information, and the call got disconnected. I also didn’t receive a callback. Has anyone experienced something similar? Would appreciate your insights. Thank you!
