Hello Student,
SASTRA Deemed to be university can be contacted to approach about the fees. The SASTRA Deemed to be university website has the contact numbers that would be redirected to the office to make sure that your questions are answered. Or you can send this query to the contact mail id given on the SASTRA website.
And since you have not paid anything to the university and have withdrawn admission , there really would be no specific issue as far as the admission process is concerned and if any dues are pending they would contact you through your mail id preferably.
