Telemarketing

Telemarketer: Is this Aniket sir?
Me: Yes.
Telemarketer: Aniket sir, I'm calling from CFHD bank. You have an account with us, don't you?
Me: Yes, I do.
Telemarketer: Aniket sir, based on your account, CFHD bank is offering you a lifetime free Gold Credit Card. It has many benefits like 1 point per Rs 100...

[Me thinking, they're offering me a credit card based on my account??]

Me : I already have a CFHD lifetime free Gold Credit Card. [Making myself absolutely clear in anticipation of "which bank" and "which card"]
Telemarketer: Why sir?
Me: Why what?
[pause...]
Telemarketer: Why don't you want the lifetime free Gold Credit Card? It has many benefits...
Me: I said I already have one.
[Hangs up...]
