I also just received a call that read Gladys Tolentino on my phone. Same as the other people posting here. A man with an E Asian accent told me he was calling from Windows and that I have an alert regarding my computer. I told him that I was sure he was not from Window and hung up.
I have recieved several of these calls.
It was funny, when I spoke to the man it sounded like he was in a bar with laughing and yelling in the background and he seriously tried to tell me he was from Microsoft. It sounds like it's a fun place to work!
Next time I'm going to answer: "Sgt. Fister, Fraud and Scams Division. This called will be monitored. How can I help you?"
