Electric Guitar Kit T-Style : extra drill holes

in the neck pocked i have 6 drill holes 1 they cocked up and put it in the wrong place then tried correcting it by drilling it in the correct place but stopped as the tip of the drill just got through the back and didn't finish it because it was too close to the badly drilled hole that they didn't fill the 6th hole is the unnecessary big one in the middle of the neckpocket im guessing they used for the cnc (invest in a vacuum plate) all the drill holes that go from the pickup cavities to the electronics cavity have all been drilled to far and have hit the other side of the electronics cavity , the wood was good but that was about it if this got past qc I'm am never touching Benton guitars again
