No response after enrollment form

I don’t know what happens next. I mailed in my enrollment form along with a free waiver for the commitment deposit about 3 weeks ago and got no response. No emails, calls, or letters.
I personally hand another one in a week ago in case they didn’t get the other one. Same thing, no response. I’m a bit worried because classes start in 2 months, and i need to register.
Is this normal?
Should i just enroll in another college?
What do i do next?

Call the School! Ask the admissions dept if they have your acceptance.
