Hi TRAI team,
I have PORTIN my number [protected] in Airtel operator and television done on 8-june-2019 on 9:38 AM.Activation update: Televerification has been successfully completed for your Airtel no. [protected]. For further update, SMS STATUS (mobile no.) to 121 from Airtel Mobile or to [protected] from any other mobile. But still number is not active. I have compiled 5 times in Airtel customer care service. But they didn't take any action. Please suggest, what can I do?
