I had a cat a long time ago that would totally ignore me after I had to scold him. He would sit right in front of me but with his back to me and totally ignore all my efforts to smooth things over with him... What I tried was I just ignored him totally and he couldn't stand that... Try just ignoring her, your "begging" is giving her attention so she is happy and don't need to "make up".....

They DO get very upset when you leave them...
