I have heard of the communication issues from several sources.
I believe they have many problems going on now, but I don't know details, only what I hear.
He tried to rob me. I went from March to December with zero progress on the gun. Then my new friend dropped in and now I will have the gun.
Part of the long time was due to my lack of knowledge on Form 3 transfer times. When I went over a bunch of this my my receiving Class 3 dealer, he informed me that Form 3 transfer times are happening fairly quickly now, and this sounded like a scam to him.
I went along for most of the time thinking the first half of the transfer took months. After my dealer told me of the short times, THEN I started to panic a little.
