Cancellation of 10(23C) registration

In case of a Section 8 company, while online filling form 10A a section selection error was committed, instead of 12A exemption 10(23C) was selected. For this application provisional registration number is also obtained. But as the Company wants 12A registration , we are willing to cancel 10(23C) registration and online there is no option for the same. Kindly for the further action to be conducted.
