Paid for full but didn't recieve

Ok so I played with the lite for a bit and was like "cool....I like it so I will buy the whole thing" so I did I paid 14.99 and it even came out of my bank. Restarted my iPad.....still just lite not the full app. I just want the full app or my money back please. Nothing bad to say it a great app. Just think it a small fixable mistake. So can someone please help me out? Thanks
