Why am I not allowed a refund for an App?
I recently installed Voice Synth Instrument from the app store on my iPhone, which comes with in-app purchases. It costs about 6 EUROS to unlock the features, which I paid, only to discover that the microphone didn't work. I then found out that you have to pay another 6 EUROS to unlock the microphone. Without the microphone access this app is pretty useless. Rather than pay again, I decided to just get a refund, but was denied this by Apple. Apparently this is not eligible. Why is this? I feel like I've been scammed out of 6 EUROS. Not much, but If I can't do anything about it, it will erode my trust with apple and the app store considerably.
