I called back number (03) 8547 9015 reached voice mail of a guy for a company called Select Careers

Received a call from this number saying they were from "Select Careers" and it was in regards to a roll I had applied for... (I never applied for a roll in the suburb they said).
I tried to return their call only to reach a voice mail, I tried again an hour later and the same thing, voice mail. I left a message both times and 2.5hrs later no response from them. Other sites are suggesting they are employment scammers and are trying to enrol you in an over priced training course as the roll you have applied for is now taken.
