Cant select other languages than English

It has a serious bug with the language selection. And a serious problem with the people behind it as they never respond to emails. I paid a 6 months subscription to find out there is a problem with the language selection. No books in other than english. Language drop down menu not working. I only subscribed in order for my kids to read stories in french. Its a rip off at this moment cause I paid $10 and Im not using it because of the bug and nobody would answer the emails.
