Yesterday, I was on the phone with a call center representative of my bank. I asked for a change to be made on my account, and she replied that she would be glad to take care of it for me. And once she put in the request, it would show up on my account in less than 72 business hours. So I politely inquired if she meant 9 business days? She 'corrected' me by saying that it turns out to be 3 business days. I decided not to push the topic further and let that be. Then I asked for another change - she made that change, and again added that it would get done in 72 business hours.
At that point, I couldn't help but smile at the situation and thanked her for the help and hung up. All I can hope for is that she realizes the difference soon, and that she is not based in India (she didn't sound like she was - I can tell when the call center is in India, because no non-desi can pronounce my name exactly the way it is supposed to be!).
