If you read the *complete* quote which you selectively edited then the position is quite clear.
You have focussed only on the throw-away line. They are not saying that they recommend or even that it's a good idea to use a "variety of tools" - it's simply an observation that the inventive could do it.
In the rest of the quote, and in the instructions on the web site (and indeed on the web sites of all other manufacturers), one is specifically told not to use a hack saw.
So the reality is that you didn't read the instructions, used a hacksaw (which you are told not to do) and, screwed up. You didn't even display inventiveness in coming up with an alternative.
To say that your position is untenable would be understating the situation considerably. Government ministers have resigned for less.
