RBL Bank — payment reminder calls

Address:

600015

Hi i have been using my bajaj platinum super card for an year now. But, for the past few months i have been receiving hell lot of payment reminder calls from the customer service. That too i receive 5 - 6 calls same day eve after i tell the each rep to add my number in dnc. The worst part is i start to get the payment reminders from the mid of the month even if the account is in current status & the due date will in the 1st week of the coming month. This is going way out of hand nowadays. I don't even understand how the bank end department works? Are they not annotating the account of the customer after talking to them? Are you not do not have an option of dnc?
