Wanted to know which age category I belonged to. Did I have other people living here with me. Asked was I prepared to answer questions then didn't ask any said he had completed his quota. Fishy

Called, didn't leave a message despite my message saying - I will deem you a scammer if you don't leave a message or sms me and I won't call back. Been getting more than usual of these - I think it might be something to do with an upcoming election. They never ask any relevant questions I want to answer anyway.

I had a missed call from this number, they didn't leave a message - as with all calls of this ilk, I just BLOCK the number.
The above comments confirmed I've done the right thing.

They said doing a research on something but didn't want to entertain further

Called, didn't leave a VM. Likely scammer.

Caller: Political call

Just received a call. He said they were doing surveys to gauge people’s opinions. I’m not really sure on what. I hung up

Customer Service Consultant started doing a Survey. I advised wasn't interested. CSC was pushy and a bit pi$$Ed off.
CSC Asked why?
I repeated my original answer, that I was not interested.

They called but did not leave a message.
