Complete lack of customer support

I bought this app about a week ago, hoping to experiment with some new tones for my guitars.

Unfortunately, if you own a MacBook that doesn’t have a line in jack, you’re going to have a bad time. None of the many USB sound cards I tried worked at all, for input nor output, even though Logic Pro X had absolutely no issues with them. AmpKit registered the USB devices as present, but couldnt use them no matter how many settings variations I tried.

I contacted customer support on their website, offering to help them debug the problem immediately after purchasing this app. However, I received no response, even though they said they’ll get back to me in 24 hours. I emailed them too, and tweeted to their @agilepartners account, and still no reply. Nobody’s saying anything after almost a week.

50$ isn’t a great deal for an app with zero customer support. I’m not looking for a refund, I just want to be able to use this app as it’s advertised.
