Took my money!

I am very unsatisfied with my FREE trial. I decided “hey we should maybe check out this free trail to see what happens in this story.” I did as I said I would and am very disappointed. I went and did what I wanted with the trial and only used the app for one day before deleting it. After a little while I come back to check how much money I have and I have quite a bit missing from my original budget. I may be mistaken, but I believe this app still charged me even after deleting it. Please change the way you set up your app or something where you can check this! I tried canceling the trial but there is no way to go to any settings of any sort! Please tell me if I am mistaken or not!
