I paid an advance fees of 10000 rupees to chandigarh university.I was officially given the time period of 90 days from the commencement of session as refund time.But it's already more than 90 days.I have mailed quite many times to them officially also the phone number they gave is switched off from quite many days.Nowadays they are not even replying to my mails.Also they are extending the refund period every time I called them.
Its really bad as I have already called them so many times.Every time they give me false hope of calling back which never happens.I am tired as a student.Please take action.
