After you file

I have been going through basically the same situation.  I actually filed Feb 1.  Same letter. I answered to no avail.  I called the IRS 3 times. I was told they were directing my issue to a department that would release the refund.  That was over 90 days ago.  Now they say that they will have until July 16th, and if the funds are not released and deposited into my account that I will need to call back and a tax advocate will be assigned to me.  My refund is not $10,000.  I have no idea why this is happening and can't get anyone to answer why.  I am beyond frustrated, as they would have no problem charging me interest if I had to pay and was delinquent.  I feel I should earn interest on how long they are holding my funds. Thank you for your input.
