Unfortunately I hadn't found this thread when I was first trying to check this publisher out in 2016 but I will say I completely agree with the first post and as an author who has been with them for three years too long but no more, I would warn others to stay away.

They don't update reports and their reports are put in by them so you have to rely on them to be honest about them
Their communication is so slow it borders on being non-existent.
They make promises they can't keep and are very shady about how they do things.

I won't go into exact details but will warn anyone that is thinking of going here to publish your books to run the other way ... fast!
