Caller trying to get me to change electricity company

called me from (03) 8372 3177.....no idea as I have "spam blocker" engaged on my mobile.......this will be a spam caller....

Received 1 call from this number & then 2 in a row straight away from ‭(02) 8363 1141‬. Sounds like it may be same d*ckheads from energy company

Called me from craigieburn

Annoying, keep calling never leave a message

Caller: From Craigieburn Vic

Called, I didn’t answer but no message left

Rang twice and didn't leave a message

Hung up straight away

Spam , trying to change electricity company

I believe it is a caller trying to get me to change electricity suppliers. yesterday had a No Caller ID from same place and told the guy, I was not interested. He became rude, so I hung up.

Serial telemarketing calls about everything from electricity accounts to solar panels. Will not give up. Blocked.

tried calling but did not leave a message. suspect marketing or scam
