Did you receive a challenge acknowledgement on a PCN fine?

I got a PCN and challenged it just a week ago. However I haven't received any acknowledgement through E-Mail or post yet. Just making sure this is normal or not normal? I don't want to assume that my challenge was received when it wasn't. Thanks very much.
