After you file

I filed Feb 10 and was accepted, it's been on still processing ever since. I called back in March and they said due to my name change it could take up to 16 weeks. 16 weeks is June 1st. It's May 4th and it's still processing. No letter no anything informing me of the delay. Are they really not taking calls anymore? I feel like I'll never get my refund at this point...
