Ratings and reviews

hi I just had an error, please check my account. it failed to render, but still charged me over 40000 credits. I need those refunded asap. I made sure I had enough credits to cover it, but it said o didn't have enough credits. Please help. This just happened but theres no way to submit an error report in the app. I did submit it as feedback. I spent hard earned money on those credits. I need you to return them.

only some of the voices sound like the character they're advertised as. They don't convert sounds like grunts or moans very well. The biggest issues is the fact that you can't do anything with the file. Sure you can share it on social media which gives the app free advertising but you can't save the file to your phone to use as a ring tone or other entertainment purposes. Feel like a waste of money. I won't be subscribing again when my subscription is up.

What's wrong with this app? I have 977 credits and the cost of credit for the effect is 224 credit, and when I press transform voice, it says "Insufficient Credits"!!! Come on do you even know Math? You can tell me directly if you can't generate! You show that option to rate you 5 star so we can get additional (useful credit) You don't even deserve 5 star!
