Caller: Call centre woman, creepily looking up parked domains

They rang me a month ago and I said to call back. In the meantime, I researched them and found a pile of complaints. They look through web domains that are parked, then call the owner and push to create a domain to sell your products. When I tried to say I'd researched them and they came up as dodgy, she got all defensive. Was so pushy and talked over the me the whole time. (Not sure that's the best way to get a customer?!)
I hung up and blocked the number.

hang up when I wouldn't confirm name, probably scam

answered and hung up immediately...no doubt just trying to fish names

They hung up when I answered

Left no message, probably scam.

Caller: Unknown

Didn’t leave message despite voicemail stating I’m a sleeping shift worker and leave message or get marked as spam

Caller: Fake Telstra

Someone calling to disconnect my account. Not even with Telstra. Hung up on them straight away.
