First of I don't want to make it seem like it's your fault. This is not my intention.
I don't know if you've ever ordered a custom knife, or custom anything for that matter (a lot of the times ordering one offs involve the same back and forth process).
I too would side with Tony, James and lessismore on this, actually I did before the pics were posted.
First, if you wanted exact, then you should have asked for exact, my guess is that the maker would have said no... It's just wrong to do that.
Second, if you wanted exact you could have just bought the one pictured (unless it was a one off, then you could have contacted the maker)
Third, if the finger grooves were the important part you should have said so.
Again I don't want to make it seem like it's your fault the knife didn't meet your expectations ordering a custom is a process and it sounds like the process wasn't completed. I can't lay blame on either you or the maker, there things that just weren't done.
And if you're totally not loving that knife, contact me, I may be interested, it looks like a fine blade to add to my rotation!
It must meet a few requirements though. (Size, maker, steel, and cost)
