My experience is the same as Bigdave's. Call them on the phone. They were friendly and courteous, and things got done, but it seems they move at glacial speed compared to other vendors I've dealt with (i.e. they took over two weeks from the time they received my return until they processed my credit).
Scroll to the bottom of:

for the phone number. Note that they're only open between 10am and 4pm CENTRAL time.
