if mac store is the inly place i can safely purchase, why alow bad product!!

I WANT MY MONEY BACK!!!!!!!!!!!!!!!
I purchased this app due to devices loading photos to iPhoto 4 times. THIS APPLE approved product picked up on only 3 duplicates, no even the ones that were quadrupled….Unexceptable business practic, im sure the developer knows this and is having a ball cashing in on others honest purchase of a product represented to do a simple task. Just purchased 2 iMacs topped out and a pro. converted from PC. now hesitant with MAc App Store. Nothing like the quality of appstore for pad or phone
