Selling solar power to businesses

Caller didn't leave a message on voicemail. Called back and got a message saying "the number you have called is not connected"

Answered call, was quiet for about 2 seconds then a recorded message said “goodbye” and hung up!!!
So I called back and a message said the number is not connected!!! This sort of crap should be illegal!! They a phishing for numbers they answer so they can sell lists of them to all those a**holes that call at dinner time from Phillipines or Indi’s trying to sell u some sort of crap!!! Go away and leave us in peace!!! 😡😡😡😡

Answered call and machine said “... goodbye” as if it was at the end of a message, and I missed the first part. I called back and it said, “this call can not be connected”

I missed this call and called back twice straight away and both times got the message saying number was disconnected

I called back number (08) 9386 5432 rang 2 times then goes to busy tone.
