We r both waman Rathod & Pranay Rathod are graduates and want to do LL.B. Three years. But by mistake we fill fees for B.Com LL.B. So.

You have not written about the college for which you have wrongly paid the fee. However, it is better to talk to the college regarding this because you will not be considered for LL.B. admission. The other way is to reapply for LL.B. course if application deadline has not passed yet.
