Probably me, when I went to try to take it apart last night to replace the button. When I discovered it was glued together, I had to pry it out.
Dude, that is what I was eluding to. I don't want to come off as bashing you and can sympathize with your frustration. You even seem to accept a portion of the blame, but why post pix of a mod that looks like its been beat to hell and back, and you yourself have hacked up trying to self perform stuff that should be left to the maker (especially since it just came back from there?) it's terribly misleading.
My guess is that mod was highly abused before you even got it. Glue may have been the least costly way to repair it to get it functioning. Chances are if major surgery was required, like very carefully retapping the hole, the cost may have been more than a replacement for the mod itself. Rob probably looked at the condition of the mod and made a judgement call.
Either way, he is a very accommodating guy. I would have called him and bounced my dissatisfaction off him. I feel your pain bro, but you are not helping yourself here.
That's a pic showing robs level of craftsmanship.
