Shiksha.com — Spam call / fraud call

Since i create a profile on shiksha, i receiving calls after calls from different different places, so called private institutions and they said that i raised a enquiry about MBA and other courses which is wrong i never raised enquiry and there is no option for delete profile or stopping calls and mails .. there calls are so frustrating and also annoying ranging minute after minute...so i want to remove my profile completely from there.
