How do I block a certain number from calling my cellphone?


I have tried calling my cellphone company (the “new AT&T”) and they offered to change my number which I would rather not have to do. Is there any other way of stopping a caller from calling? Somehow someone got a hold of my number and calls at all hours of the day and night and it’s starting to scare me.
