If your refund was sent to a bank account under someone else’s name, or you entered the wrong account or wrong routing number, your refund will be rejected by the bank and will be returned to the IRS. You will eventually receive a paper check from the IRS, mailed to the address you entered on your return.
Expect that to delay your refund by at least another two weeks or more. You may want to contact your banking providing for further assistance. Or you can also contact your local IRS office. See this IRS website for local IRS offices - http://www.irs.gov/uac/Contact-Your-Local-IRS-Office-1
