I called back number (03) 8210 6720 rang 5 times then goes to busy tone.

Had multiple calls from this number. Indian telemarketer addressing me by name (???) and inquiring about the 'discount on my electricity bill'? I live at home with my parents and don't have an electricity account in my name, so obviously some sort of scam. Did not claim to be from any particular company before I hung up & blocked number.

Received phone call at 1.33pm today, so it must have been a legitimate number till then. "Sorry, no results were found for (03) 8210 6720" when I checked to see who the phone call was from

some c*nt selling electricity

I called back on (03) 8210 6720 and got the message that the number was not connected. Telemarketer, scam?
