I had received a call from rbl offering me with a new credit card without any membership fees as a scheme. I agreed to the same since there was no fees but as soon as the card got delivered i got message of 3538.82 /-. Kindly note at this stage the card was not even out of the package and i never even changed the pin yet. I started getting calls asking for the payment and when i informed that i do not need the card as i was given wrong information from the customer care guy, they said they will get back to me.
Right after 5 - 6 days i got a message that 1000 rs was deducted from my rbl card (I did not yet set the pin so no chance of me accessing the card)
When called the rbl bank i was informed this was for credit card fraud (Ccf) which was automatically approved by them... This was the point when i lost my patience and i again called them the rbl to discontinue the card right away.

Still my card is active and currently i am getting threatening calls and asking me to make a payment of 6382.16 /- (Surprisingly the card is still the parcel which i received on day 1 without even having the card with me i am supposed to pay 6382/-)

This is how they have been cheating people. I in no circumstance going to pay this # a single penny no matter what actions i have to take.

I am just worried about my credit score since this nuisance is affecting my scores which i really don't appreciate.
