No feedback on delivery status

Though worldnet has been very helpful before, this latest transaction did not go well at all and I am quite nervous about receiving my documents. They never got back to me after I sent proof of payment, even when I sent a follow up email. I phoned twice this morning to check on the whereabouts of my documents, and was told I will be phoned back. That didn't happen. Phoned again later and was transferred to a line that never picked up. Waiting for urgent documents.
