Harassment by Carzonrent Bangalore.

I have a payment due at Carzonrent Bangalore, the issue was that the company had made multiple billings on my credit card due to which i denied them payment.

These guys did not get in touch with me for 6 months, after 6 months they are treating me that they will file a police complaint.

I know there is a fault from my end on not making the payment but i just need 48 hours of time in order to settle the payment.

What do i do in order to get a 48 hour window to make the payment.

Please help me.
