won’t open - stole my money

I bought this app, was able to open it once and then nothing—no count down clock, no nothing. I can’t get it to open, I only have the icon on my dashboard and no matter how many times I click on it nothing happens. I guess I’ll go through my credit card company to refute the charge, since I just got 99 cents taken from me for nothing.
