Narayana E Techno School — No proper communication

I also want to talk to head office member regarding Leaving Certificate of my child. I applied Leaving Certificate at Nalasopara (West), Mumbai, Maharashtra branch on 8th April, 2022 but still not received. They told me Leaving Certificate will be issued by our Head Office in the month of June-2022. But i need LC with 10 days to take admission in other school. There is no contact number of Head Office. No one is helping me.
