Five days ago I paid 500$ for 50 units of Botox. I still have a lot of movement in my forehead. Did I get ripped off? (photo)

I went to a Med spa instead of my regular doctor and I do not have another 500$ to spend at my regular doctor. I got 20 units for my crows feet (10 on each side) then 12 for my glabella and 18 in my forehead. I haven't had Botox in three years but I don't remember it taking this long to work. Did they dilute the Botox too much? I used to get the same amount at my plastic surgeon with no problems. I am very worried I have to walk around like this if they don't fix it. Please help
