"The App description did not say anything that it would not do what I was trying to do."
You've already had 9 refunds? You understand that apps are sold on a non-return policy, presumably. You bought an app that didn't claim to do something that you wanted from it, and now that you've found that it doesn't, you want your money back.
Perhaps you've failed to explain your point properly but I can't see why you expect any sympathy from users here, not that it would make any difference. Only the store staff can issue refunds if they think appropriate. Chalk it up to experience. You could even contact the developer in advance of a purchase if you want to be certain an app does what you want. Then if it really fails to live up to the promise you would at least have a better argument for a refund.
So I assume then, that you don't operate on a principle of learning by - or from, your mistakes? (It's never too late to start.)
I have to be frank, I too, don't see why you think you're entitled to be subsidised or refunded, when you fail to do your research properly, or rush instead of taking your time.
No one else's time should be taken up as a result of your haste or lack of research. It's actually rather selfish of you to expect it.
