Well, that's not what you could reasonably call 'very blonde' but the statement is definitely open to misinterpretation as it stands. A gold blonde level 7 for instance looks completely different to a cool blonde level 10.
Did you show her any pictures of what you like? If not, look on Pinterest or similar and find some images to show her what you want to achieve.
I'm guessing you wanted something multi dimensional looking rather than a flat all over colour but you need to be much more clear. I'm not surprised she misinterpreted your request if you told her to apply 1 bleach, 1 tint (?) and a dark blonde. A dark blonde would be a level 6 or 7 and you definitely don't need to go that low. Plus you only need one darker foil to every 3 or 4 lighter foils for a subtle hint of depth.
Is she fairly newly qualified, do you think? I wouldn't really be interested in you telling me what colours to choose or in what ratio. I'd be more concerned about obtaining a good consultation and understanding exactly what you want to achieve and discussing how realistic your expectations are and the potential upkeep required.
Tip for future appointments...if you don't feel 100% confident that your hairdresser understands exactly what you're after following a detailed consultation, don't go ahead with the service. If the consultation is very short or non-existent, you're unlikely to be satisfied by the end result.
