Xulon Press review: Xulon trying to recover money from my deceased father

Here's a new one, my father who passed 7yrs ago received a message from Xulon trying to extort almost $400 from him with a veiled threat he would be taken to collections if he doesn't respond. My father had written a book about his experiences of being a Christian physician and apparently used Xulon's services to what degree I don't know. Unfortunately if any entity or person claimed to be a "Christian" he would immediately put his undying trust in them so he was ripe to be conned and this company was no exception. So here we are 7yrs after his passing with Xulon trying to extort a dead man. They gave a number for him to call back immediately to make sure to get this settled before they take action. I just laughed when I heard the message and they can do what they want as far as I am concerned, but imagine, 7yrs after his passing they come up with these "unpaid charges". My advice is to stay away from this Unchristian company,
