Well, at least you were actually able to get someone on the phone.
My first order last year was irritating until I just accepted that they are not the fastest processing shop on the planet.
First lower build was problem free.
Second one (just received last week - now I am going to go double check it to make sure all the parts are there) was a bit faster. Stripped blem lower, MIAD LPK, SSAE, A2 stock kit. First look appeared to be complete.
