So are you saying you can't prove you didn't place the order?
They're saying you ordered it, that's what they're saying.
These are respected posters we're talking about here and you have no way to counter their claims?
It's pretty clear, then, that you placed the order.
That seems to be the end of the story, unless you want to keep going around in circles.
Of course, you end it all if you would just take the time to post the proof and put these respected posters in their place.
