Tax Refund Delay : personalfinance

I mailed in my paper return in mid-March by certified mail. I received back the USPS delivery receipt on April 22. When checking the “Check Refund Status” search tool on since then, I consistently get the message “We cannot provide any information about your refund.” My call to IRS, after following the phone prompts, results in the same message.

My next step is to get an appointment with the local IRS office to see if they can track the return (if I can ever get through to their appointment line). Is there anything else I can do to find out when I can expect to get my refund? It’s been a minimum of 8 weeks wait already.
