I'm not surprised. At all actually.
I haven't personally dealt with these guys (I don't drive a Japanese car) but a buddy of mine with a TSX has and the experience was nothing short of crap. A simple coilover install was a fucking gong show by the time everything was all said and done. Appointments were rescheduled, the coils weren't even installed properly in the end and to top it off they wanted to charge him extra when we went back to get them to fix the problem, riiight.
I've been around cars and shops since I could walk and I've never seen anything like this.
