What she now needs is support from people who believe in her.
For her to improve on her PR skills, she has a rather long way to go. She desperately needs voice training and lessons on conversational English.
Her managing agent is not doing enough to help her. If an interview did not go off right, the PR person has the right to cut in and ask for repeats. I am not surprised she was left alone to rot. You could hear from the Indian interviewer's voice that she was somewhat giggling at the bad replies.
It took me 3years to train myself to face media (without script) for formal business dialogs and 4years for voice training on diction (averaging 3hrs a day). If she can be up to speed within 3mths from where she is now, it might take a miracle.
Meanwhile, her only tricks are to talk less, smile more and let the PR handle the media.
