Cadila Pharmaceuticals — Uan portal kyc update

Address: Baruipur, Bhattacharya para,behind bank of Baroda

Respected sir,
My name is Swarmalika Banerjee. I was a field officer in Cadila pharmaceuticals limited from june 2018 to March 2020 as a field officer in kolkata 3 head quarter in Magna star division. My uan no is[protected].
Now i need to update my bank account details in uan portal which requires a digital signing from my last employer which is Cadila pharmaceuticals.
I have contacted Falguni Chhavra mam who was my hr when i was in the company but i can't get any answer from her. As i don't have any other contact details i come here to resolve my problem.
Please approve my request for updating my bank account details in UAN PORTAL. If you need any documents from my side please let me know.
Regards,
Swarmalika Banerjee
