For the record: recently bought a Charge Plug 0, advertised as having a drilled rear drop out. Turned out that mine didn't. Entered into correspondence with Charge; eventually they checked some more bikes and admitted that someone seems to have forgotten about drilling the holes.
I was advised to use P clips and come back for the 2017 bike which will have holes added.
