Blunder with the supplements! Please help

<p>i'm an international applicant from India.
I've been using the assistance of an education consultancy to aid my application process. Recently, the the agency submitted the supplements to the colleges without my consent. In the space provided for the essays, they have filled in "enclosed with documents" as they had initially planned to send a paper copy of the supplement along with school transcripts, recommendation letters, resume and attestations of my extracurricular activities.
Now, i'm really worried about this whole "sending by mail" process. Is this an accepted way of doing things? To send the main application online and the supplements by mail?
Will it annoy those at the admissions office?</p>
