See who's calling

This number showed up As the name ANGI as like I had already stored the number in my phone but I knew I had no names in my phone as such as ANGI so somehow they calling making it look like you know the person just cause it shows up as a stored number but when you go look up the name in your contacts you don't have that name so now you know your not crazy. And when you go back and check your call log for the name is not there is just the number that shows up no name with the number so you text it
