Respected sir/mam,

With due respect i want to tell you that i have registered in josaa as well as csab 2018 and also has paid the participation fees 36500/- with the following details as mentioned below.

Manvendra kumar hati
Jee main roll no[protected]
Jee main marks - 81
Jee main crl - 93174
Class 12th percentile - 91%

And, as i have successfully filled and locked the choices in csab 2018 portal by paying seat acceptance or participation fees as well. Also, i have filled "metallurgical engineering (Nit raipur) as one of the branch choice.

But, after first round of seat allotment and opening and closing rank statistics, it has been observed that in nit raipur (Metallurgical engineering) the opening rank is - 56758 and closing rank is-104124. And, inspite of being my rank 93174 which falls in the above opening and closing rank, i was not alloted any seat in csab first round. Even i was not informed if any mistake was done by me also during choice filling.
I have also tried to contact the helpline number, but, no one was reachable.
Kindly, help me to know the reason of no seat allotment inspite of having the rank in the range.
I shall be very thankful to you.

Thanx and regards
Manvendra kumar hati
