Answered twice there was no response then phone disconnected

Got this call from number on my cell.  Answered and the caller asked for a "Heather Burns."  (I had received a call from a different number -- 510-981-1515 -- earlier in the day, asking for the same name).  Told her that no one by that name at address and do not call again.  Also asked who this is and she said "US Bank" -- maybe, maybe not.  The number has not called back, but seems like a scam.

web search points to Dynamic Safety Inc. as the owner of the number.
