Rang and hung up . Left no message. Did a search online and all I found was that it's a telemarketer

Caller: Cold Caller

Called a business, but the subcontinent accented gentleman in a loud call centre didn't know whether he called a business or a residence. He says we are getting an AGL refund, but also asked who our energy supplier was. He hung up without a word as soon as I said he won't be able to speak to the business owner. Most likely a scam.

Suspected spam. No message left. Last 2 digits in their number are in sequence with a few previous reported spam calls so clearly they are working their way through a block of numbers.
