I called back the number 0432 478 827 and reached vm that did not mention the company name

Caller: Morgan from an energy saving company

Not selling anything he says but knew my name on a private number and wanted to inform me about the government rebate. He stated my details came from www.Ausland.com.au I disconnected the call but then rang back immediately and it was disconnected.

17/09/2019 18:40hrs - received a call from 0432 478 827 by a guy (possibly telemarketer & possibly Indian or middle eastern judging by his accent) who greeted me with a personal first name and surname (for example John Smith - not my real name in conversation) as if though I was that person - I did not acknowledge his personal greeting but responded by saying "you've called ABCD Pty Ltd (not my real company in conversation) - how can I help you?" - he persisted calling me by the personal name - I repeated that he was calling ABCD company & how could I help him - he then called me by the personal name he initially used and then in a soft & deliberate voice said "go f*ck your self" & then added "you sound like a chimpanzee monkey" - I cracked up laughing and said he was being recorded and that I would report him to the authorities - why was he calling & what did he want - he then repeated the name calling and said that I was being rude not letting him talk - I said "excuse me - you called me on my company line & now your telling me to go f*ck myself? What are you trying to sell and what drugs are you on?" - he repeated his obscenities and wouldn't get off the line - I then put the phone down without hanging up but could hear him repeating "...hello - monkey - are you still there - hello chimpanzee monkey you f*cker..." and then he hung up. Interesting phone call - I tried calling back his number 0432 478 827 from a different company line only to get a message "Optus advises that the number you have called has been disconnected.." - This is not the first time I received a call from this guy - I recognize his voice from several previous calls over several months - he always starts off nice wanting to sell something (I think maybe solar panels) and then reverts to obscenities and name calling when he feels he's not getting anywhere with his sales pitch. Has anyone else out there received a call from this joker - does anyone know who he might be and how can he be calling from a disconnected mobile number? I feel that this is a dangerous character who has somehow got a database of numbers he keeps calling and might even have private addresses linked to those numbers he calls. Would love to know others' thoughts.

Caller: Solar Energy Australia

Heavily accented caller claiming to be from Solar Energy Australia. When I said I wasn’t interested the caller said, and I quote “f@&k you then, f@&k off” Quite the charmer really.
