Look through your spy hole or window
Are you expecting anyone?
Do you know them?
Check the identity of the caller before opening the door
Don’t let any caller pressure you into making a quick decision
Don’t feel you are being rude or uncaring by saying ‘No’, your own safety is more important
If you are not sure, don’t open the door.
Do not leave your property; refuse to be escorted to a bank or ATM
