How long to post credits?

[hostmaster]

In general, how long does it take for credits to post to your account if you
fax over a credit card form? I faxed one over yesterday around Noon ET and
haven't seen the credits show up in my account yet. If I recall in the past,
once I had to actually follow up to make sure it happened, and the other
times it seemed to happen a lot quicker than it seems to be taking this
time....
