hello,

If you have locked your college and paid 50,000 but you have not physically reported to that college then obviously your seat get cancelled and also you are not eligible for the refund as it's your fault you have not physically reported. If you had surrendered your seat online(at the time of announcement of 2nd round results) then you are eligible for the refund. Also you can always contact to comedk authorities for the complaints.

hope this will help you

all the best!!
