It's A Temporary Issue,
I Think Airtel Testing New Mail And Message Systems,
And Developing Service Codes System To Make Service Engineer's Work Easy & For Us We Can Share Feedback With Airtel By That Codes.
[Word Feedback Reminds me that they can add feedback taking systems before accepting complaints, this may makes their international market image higher than it is now. Because soon they become World largest DTH after merger with DishTV & D2H.
In Telecom Business They Takes Feedback Instead of Complaints First. (Not First, Always)
To Show They Receiving Less Complaints.]
Like this code, they can bring facilities like OTP, So that only the complaint lodger should be served. So This May Stop Illegal Interchage Of STB & Multi Connections.
Also May Step To Stop Illegal Connections Outside India.
Means They Doing Something For Their System.
By The Way For Me It's Showing Someone Else's ID & Mobile Number (I Find On True Caller, That's From Punjab) But My Balance & Due Date Is Correct.
