Airtel — gstin required for billing

Address:

Jamnagar, Gujarat, 361008

I have corporate cug connection in state bank of india with sim [protected].
For reimbursement of monthly bill, we have to insert gstn, kindly give subject number so that i can apply to my company for my bill. This complaint is not against the organisation but for the general information required for smoothness of billing monthly cycle. Thank you very much
