Back in January we received an invoice for our subscription to Classification Web. We paid it from our deposit account. Since then we have continued to receive invoices and no replies from LC. We have e-mailed them many times. We call, but the voice-mailbox is full. never does a person answer. Now they have cancelled my access, since we did not paid the bill. Only we did, months ago. What is going on at the Cataloging Distribution Service? Anyone have a secret to contacting them?
