Rude coworker

I’m in fulfillment(seasonal) and I really love my job! I have gotten along with everyone except for one. Whenever I need an item I always ask the leads for the specific department and are always willing to help, except for the one. She always ignores me on walkie and one time I was able to find her and I asked for help on this item and she deadass rolled her eyes at me. She’s very rude and snotty and just makes my day miserable. I dread asking her for help because SHE NEVER HELPS. Idk what to do and I always inf the items in her department. I’m not sure why she’s very rude to me? I’m pretty quiet and I can get along with others easily. Hopefully one day I’ll get on her good side lmfao.
