Changing intended undergraduate major after applying?

Hello everyone
I really want to change my alternate undergrad major from physics to math and cs. Does anyone know how I would go about doing this? I’ve emailed the admissions office twice through their site and once through gmail, and haven’t received a response. I asked my counselor, but she said she was busy. Can anyone please help me?

I don’t think there’s anything you can do about it, but if you get admitted, you can always change your major while you’re at the school.
