This number keeps calling me and I am only 12   Someone help me

You need to get your mom or dad to speak with your phone service provider. They can block this if your phone does have call blocking already.

Do you know how to block a number from calling you in the future. On my phone if I put my finger on the # and hold it there a box appears to give me choices, one of them is "Block number...: I tap that selection and my phone requests me to confirm that is what I want it to do. Tap Block and it's done. I hope this will work for you so you won't be bothered any more. Good luck.
