Same here, I applied for a renewal 6-months before in March. I've been working on the extension slip since Sep 30th, being thankful and praying everyday to stay sane.
I don't think it's the wrong place, my attorney also mailed the VAWA c09 EAD renewal package on 03/06 to VSC and we've not heard back from USCIS as well. Any idea how long is it taking for an EAD renewal receipt notice?
The wait time for EAD in VSC is 15 months !
