Doesn’t do what it claims

I’ve just purchased this app becausse I have photos on my computer that I would like to share on Instagram. The uploader does not work at all. Does Apple offer refunds for the purchase of apps that do not deliver? This is the first time I have purchased an app that did not do as it says. I hope it’s just a glitch and it can be fixed soon, if not, I want my ten bucks back!
