New India Assurance — correction of vehicle no in insurance

Address: 603303

Hi,
I tried to renew my insurance no[protected] customer id po48525716 via quick renew option in that i wrongly entered the vehicle no as tn19az1852
But the actual vehicle no is tn19az1851. After noticing this i stopped the payment and try again but the form get locked with the wrong vehicle no and not allowing me to correct it.
Tomorrow 15/03/18 is the last date for renewal.
So kindly make some immediate action to solve this issue

Regards,
