I tried the application for free, after some time I noticed that it crashed a lot, it was hanging on start and never started. I tried to find some solution - reinstalling IOS, application. I even bought a monthly plan. But the problem still appears. I wish I could take it back and never install it.
How do I proceed with refund (I used CC to pay)? I already wrote the ticket through the application, but I dont know how long it takes to get feedback.
