Called me twice, first one they hang down immediately
Next one they waited about 30 seconds and then hang down.
Looks like an scam

Called back straight to hold music definitely a scam in my opinion

Caller: Foretrade

It is a Crypto currency trading company that are trying to get you to trade with them

On answering they hung up

I have received three calls from this number in the last week. I called back today and received an automated response.
"The number you have dialled is not in service. Please check the number and try again. Goodbye"

I assume that this is a scammer or a robocall

Caller: Energy bill comparisons

Was called by this number today. Claimed to be energy bill comparison service and would forward my call to energy company with comparative prices.
Conversation replies were delayed, could be overseas call centre porting via Sydney number

I called back the number (02) 8317 1481 but the phone just kept ringing
