@amalrakoff lucky indeed, since until May I had a Vi postpaid, and was suffering to the sound of that lady.
@Samuel, I never figured this out since I do not make a lot of calls. But I was confused that sometimes the call would just connect, some times I would get that torture. I will see about this three-call thing, thank you so much for that information. Maybe if I call another number I have thrice, disconnecting as soon as she starts with her monologue, I might be able to get on with the day as I am supposed to. If this works, this will save me a lot of unnecessary annoyance.
It is not funny when you are standing at an SBI ATM with your father's debit card, and you have to call him to get the OTP since someone in the banking industry thought mobile network hai, advantage liya (oops, I mean, torture kiya) ja sakta hai, and you get this lady's voice. Biwi nahi hai meri wo.
What if I have an emergency, will I like to listen to this? Nobody thought of this. Just decisions from the "government" to "govern" people, in a completely upending way.
