Shiksha.com — deleting a review

Someone had made a review on my college negatively by logging in with my account. So i want to delete it immediately. Please help me to delete it. I wanted to get that deleted as it is not an honest review made by me. So please delete it as you can understand i would be blamed if something happens. Kindly look into the matter and do the needful. Thank you in advance and hope my issue is resolved.
