They're incredibly opposed to giving out the phone numbers for individual baggage offices. Unfortunately calls about baggage usually go to the ICC, which feels very infuriating as they're so far away.
The one time I did manage to get a local baggage number, the woman warned me (her words, not mine), "I don't ever answer anyway, because I can't understand what the Indians are saying." This perfectly explained why no one could find my bag for 10 days.
