Very late appointment date

[xyz]

My mom got an appointment date for interview at Mumbai consulate thro' the VFS at Ahmedabad. She got a date in June, which will be very very late. I need her to be in US by June 1. This is posing a great problem for me.
Is there a way, I can track the vacancies and try to pre-pone her appointment date, just as the facility available thro' tts visa services. I don't see any option for Ahmedbad on tts.
PLEASE HELP.....

Mumbai (and therefore Ahmedabad too) is handled by VFS. Rest of the consulates are handled by TTS in India.

If you are from Ahmedabad, whatever VFS provides is all you have.
