Airtel — reparding plan activation airtel for corporate number.

This is with reference to the airtel postpaid number.[protected] which is in the name of innovation alchemy consulting pvt ltd. Yesterday i requested to activate the plan: ir @3999-30days pack, unlimited incoming (Travelling country - india to spain). I sent an request to [protected]@in. Airtel.com from register id. [protected]@innovationalchemy.com, because we need the plan activation from 8/8/2019. But no reply from airtel team for the plan activation. Today i spoke with customer care, the lady is telling we can't do anything, you have to wait for the reply. Or else we have to go & visit the relationship centre at this time (9.30pm). What is wrong with airtel, you people are not responding to the email or calls. Then who is the responsible person we have to speak?
