False advertising

Just want to express my dissatisfaction at how the McDonalds in Noordwyk is running things. I mostly go there to by a Happy Meal for my son. For the past two months, everytime we go, the toys displayed on the menu on the drive thru are not what you get at the window when you collect your order. For example the past two weeks its supposed to be robots for boys, and pony's for girls but instead we are offered a toy that was being given about 3 months ago. It is very disappointing for my son as he has about 5 of the same toy from months ago. If they are out of stock or something, why is it not mentioned on the menus like they do with other food and drinks? Also when we try to ask if they have anything else other than the old toy, most of the time its a no with an attitude and told to go exchange it at another McDonalds which is just an inconvenience.
