Leaves no message. Therefore, I won't be calling back.

Sounded like a giftcard scam, it was an automated message saying they were with some fraud team and following up on giftcards I apparently purchased. I hung up.

Caller: It’s a health insurance comparison help line..

It’s not a scam line.. I filled out a form to get a comparison on health insurance but chose not to go ahead with the enquiry as I only want ancillary cover and these lines always want to quote on private insurance.

I missed the phone call and I don’t know the number.
