these are genuine questions because i wasn't there and don't know the important details. i'm not trying to criticize either you or the quilter.
did you discuss what you hoped for with the quilter? or did you leave it up to her to design the quilting?
everybody had different tastes. if you left it up to her, i'm sure she did her best to put down a design she thought was lovely. you and she may just disagree about that.
you should only complain that you didn't get what you wanted IF you made what you wanted very clear before you left it with her.
if it was a misunderstanding, or a case of the quilter not having enough information about your preferences, then make sure to be more clear and precise next time.
if you know you didn't get what you asked for, talk to her about it. she can't fix a problem she doesn't know about. ;-)
