Is it worth the time calling the IRS?

My husband and I filed our joint tax return on February 1st. We had one W-2 each, a mortgage interest form (made no difference, so I doubt our tax lady even entered it), and an education form. I got education credits for being a student and I knew these weren’t being accepted until mid-February, so I wasn’t surprised that the return wasn’t accepted until February 18th. So, today is day 21 after it was accepted and, according to the Where’s My Refund tool, our return is still being processed.

I thought maybe it was still a delay due to the education credit situation, but the two people I asked that filed similar returns got their money in a week or two. Other than the education credits, we had NOTHING complicated. There’s no reason we should still be waiting for the refund that we desperately need. I was told by H&R Block that we’d receive a letter if there was a problem, but we haven’t received anything.

I attempted to call the IRS to see what the hold up was, but my wait time was over 30 minutes, so I didn’t wait. Is it even worth calling them or are they just going to give me some generic answer that “some returns take longer,” but nothing specific to our return?

Is anyone here still waiting after 21 days?
