Rescheduling after accepting the interview call from accenture?

I accepted the accenture’s interview call for 17th January, Bangalore. But due to some circumstances I will not be able to attend on that date…so can I reschedule it?? if yes, then what is the process of rescheduling?? or if I will not attend it then can I attend the later drive of Accenture??

You cannot reschedule once you have accepted the call.

If you do not attend, you will get a “No Show” status and there is very less chance in future drives.
