Airtel's Marketing Strategy

Recently I have had a funny experience with Airtel. It was related to their Hello Tunes service. I used to use  Another Brick in the Wall of  Pink Floyd  as my hello tune and it was so pathetic that in post of the phones it sounded horribly weired. So, I decided to drop the service by calling their customer care helpline number 121. Here goes the conversastion:

Airtel: Welcome to Airtel, my name is Reshmi. How can I help you?

Myself: Hi Reshmi, I want to discontinue the Hello Tunes service in my phone. Could you please tell me how can I do that?

Reshmi: May I know, sir, why do you want to discontinue it?

Myself: It's becoming too costly for me. 30 Rs. per month is no cheap for me.

Reshni: Sir, we can give you an offer. I will make you unsubscribed and subscribed to the same service and you will get the service for six months at a meagre cost of Rs 15.

Myself: Thank you for the offer, but currently I am unable to bear the cost.

Reshmi: Sir, for last three months you have been paying more than 600 Rs per month and 15 Rs is too low compared to that.

Myself: Little drops of water, little grains of sand, make the mighty ocean and the pleasant land.

Reshmi: I am sorry ?!#%$

Myself: Nothing. The tring tring sounds better to me than the Another Brick.

Reshmi: We have wide range of songs, sir.

Myself(rudely): I, simply, don't want that service.

Reshmi: OK Sir. Please type STOP and send it to 121.

Myself: Thank you.

I recalled my interview days. But her voice was sweeter than the people who interviewed me.
