Was facing some issue with a thanks benefit but airtel cc rep told me my black tier has my number 9933xxxxxx as registered number (which is ACTUAL postpaid number of my airtel connection) but the registered number with my airtel postpaid connection (mobile 4G 5G one) is 9647xxxxxx (which is NOT any airtel number. In fact that's my alternate number which is of Jio). How to fix?
