El responsable de reclamaciones no ha respondido en 15 días, ¿debería acudir ahora al GAC? (India)

Hi all, my Instagram account (personal, around 1,200 followers) is disabled since 26 Sept for 'account integrity'. I did the appeal in the app and it was rejected the same day. On 6 Oct I submitted a complaint to Meta's Grievance Officer for India through their form. I got an acknowledgement mail but no resolution till now. As per what I read they have to resolve within 15 days, and that time is over. Can I now file an appeal on the Grievance Appellate Committee portal? What documents do they need? Has anyone here done it for a normal personal Instagram account? I read about a Delhi High Court case in August where the court asked Meta to put on record why it took action on an Instagram account, but that person was a stock market adviser with a big following, not a normal person like me. Any guidance is appreciated. Thank you in advance.
