Tax Refund still showing processing since Feb 10

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. Some of my documents (1099-Cs) had my old name. 16 weeks is June 1st. It's May 18th and it's still processing with no updates no letters, nothing. Are they really not taking calls anymore? I feel like I'll never get my refund at this point... I changed my name on my SSN, if they needed proof the old name was me i could send them my court papers but no correspondence at all. Do I just wait indefinitely? Will I ever get my refund?
