Airtel — Unable to receive SMS since over a month

Address:

GOA

Airtel has blocked my incoming SMS functionality. Since submitting a Mobile Number Portability (MNP) request, I have been unable to receive any SMS messages. Additionally, I did not receive the MNP porting code. Subsequently, I decided to continue using Airtel as my service provider. However, since that time, I have been unable to receive SMS messages from any phone number, including one-time passwords (OTPs) and personal messages. I am deeply disappointed that Airtel has resorted to such an obstructive course of action.
