Utter disappointment - 2 different takkie sizes

I ordered the Adidas rivalry online from Sportscene for my daughters birthday, which is Friday. The order was delivered this morning. After I got home from work I opened it to check that all is in order. To my horror, the talkies are completely different sizes. I ordered a size 3 the one shoe is a size 3 and the other a size 6....what in the actual hell? Two different takkie sizes? Are these items not checked before it's packaged? Who gets something like this wrong? What am I suppose to give my daughter to open as a gift on Friday?

She is so excited, as a struggling mom I don't buy her name brand items. I was excited to see the look on her face Friday, what am I suppose to do now? I am highly upset and utterly disappointed in this
