Paid $150 for crappy ultrasound pictures

I paid $150 for a nice 3d ultrasound package but my baby girl was facing away so they couldnt get any photos so i walked out with nothing. I came back and the same thing happened except they handed me two pictures of the side of her face and you cant see anything. So it wasnt the ultrasound techs fault but im still extremely disappointed. Now, my question is they have a money back gauruntee sign on their front desk that states if youre unhappy with your photos youll get a refund. Do you think i should be able to go back and get a third scan done? All i want is 1 decent photo.. I dont even want my money back as long as i can see her face a little more clear. Or do you think i should just deal with it and move on?
