I can't help you with a Wells Fargo contact. However, I would have your agent contact the managing broker of the listing firm and request evidence that your offer has been submitted and is awaiting acceptance. Unfortunatly, some banks are overwelmed with foreclosures and short sales and do not have enough staff to handle the work load efficiently. Good Luck!
