Called my mobile number. No message left. Blocked.

Call 5/16/17 asked for my fiancée by name through my cell phone. Said it's 10:35 in the evening who is this and what is the purpose of the call. They said no message will try back and hung up. Can't trace the call or call back. Sounds like some scam.
