After renewal of my credit card I got a call too from HDFC Delhi from some Malhotra saying that I have so and so benefits on my credit card as I was their “chosen customer” due to “my good record with the bank.” He wasted my half hour telling me about the benefits and then at the end said about 7999 being deducted. I straight away denied that and warned him about deducting anything. He was persistent and next day some Mishra called and started the same thing. After talking sternly they backed off.
So much for being a “chosen customer” : )
