ICICIcredit Card — Height of faking and hiding things to customer

I submitted an EMI request for an amount of 10000/-. The service request number is SR97945187. Now, thwy answered me "We sincerely regret that at present, our internal policy constraints do not permit us to convert your purchase transaction into EMI on Call ". No precise details nothing. I want to close this card. and end up with all relationships with ICICI. The worst ever bank service I've ever seen.
