Voice changer Free ? Why you mention on internet its completely free if its not?

Hi, I search for a good Ai voice changer  and  too bad that   even yours are limited by using  by credits. Why you mention on internet when people first saw your software that the service is completely free? When I download Voice.ai voice changer  what was my surprise when I realized  you want pay for any other progress.. even when I create my new voice  no credits earn as was mention. and Train voice   for that big amount of credits? I am very dissapointed about that. My uploaded voice  even 5times failed to  get upload and when I finaly get it ready I find out you want alsoo pay credits for "my own  uploaded voice"?
