Unable to get Incoming Call Barring service Code

By consumer On 8 July 2020 In Telecom companies

Tried all Airtel Customer Care Numbers 198, 121 & 9810198101 but unable to talk to any customer care representative(CCR). All the numbers keep giving IVR options but no option to talk to a CCR. Airtel does not provide any chat option also. Please Help me to get the code to activate All Incoming Call Barring Service.
