Caller: No Name

Call received from this number (to my mobile) asking if I had noticed my electricity rate/costs increasing and advising that better electricity rates/costs were possibly available if they run a comparison. Note - I am in a state with only one electricity provider so before answering any questions I enquired what state they thought I was in, they replied "Victoria". I replied incorrect, which they immediately replied, "get lost, you can get lost", then hung up.
