I called the number back & got a recording saying I had reached Careflight a not for profit organisation.

Keeps calling each day. I let it ring 7 times before picking up. (Usually this weeds out the telemarketers quickly) Nobody answers so I hang up quickly.

We get the same. Just another scammer expecting you to call back on your mobile - be warned they can get access through a smart phone but not a landline.

This number continually calls and just hangs up, waits for me to answer then hangs up.
