We apologize for your dissatisfaction with the product. Subtitle generation is processed in our cloud (It has always been this way.), which can lead to queuing and processing failures during peak periods when there are many tasks. In response to previous feedback from many users regarding queuing and processing issues, we have added more servers and implemented a limitation on credit-based processing to provide a better user experience for all users.
These credits are currently sufficient for over 100 hours (and 200 hours when you process with a .srt file) of video. These credits can also be used on the website and for all other Fab brand FabCloud service features. If you require more, you can purchase additional credits at a very low price.
If you are still not satisfied with the product, you can require a refund by contacting us (https://unifab.ai/contact.htm), and our customer service staff will contact you as soon as possible!
Once again, we sincerely apologize for the dissatisfaction caused!
