Yeah, when I was a kid I had to swallow nasty medicine too. And yeah, it made me better. Does that mean my son shouldn't be allowed to have medicine that tastes better and makes being sick just a little more tolerable, because the nasty stuff works just as well? Years ago they didn't have a polio vaccine either, and many people survived without ever having polio. But you can be darn sure my kid has been vaccinated for it.

But all of this is beside the point. The OP paid for something she didn't get. She is entitled to a refund.
