I received a robocall from "DBS" that informed me that the bank tried to get in touch with me several times in regard to my personal account with DBS. The message was in Mandarin. I was asked to press '3' to speak with an agent.

As DBS does not refer their service providers as agent and would not use a robocall to call their customers.

Hope by sharing this experience, it will help warn others of this scam.
