Did you try (800-275-8777)? I think that is a national phone number for USPS. It might take a while to get them to drill down to the local post office but that may be your best bet. You could also just go to any USPS post office and see if they can help.
I'm sure there is a way to get your mail forwarded with a phone call but it may be complicated as USPS won't have an easy way to know who is asking them to forward your mail.
