I forgot to mention one very clever one is ; scammers call on your landline pretending to be from your bank. You are naturally suspicious, they say, no problem just call me back on our head office number. You then call on a number you know to be correct, and they answer, the trap is sprung. You see when they call you they do not disconnect the line when they say call us back. You then call not knowing it's an open connection to the original call 😱
