How to deal with annoying brothers?

Hey. So I have two little brothers and they are very annoying. I tried telling my mum about how they always annoy me and call me names like (stink, fat, ugly etc..) And she only says "Just ignore them". And it is so annoying because it is not helping me, because they try to get my attention no matter what so they can annoy me. I have really short patience so idk how to handle this.
