My tree-like houseplant's branches are turning black & leaves fall off. Don't think it's root rot though.? - how can i keep the leaves on my houseplant shiny

I have a tree as a houseplant, is not a fig, I do not know what the name though. The first had ended with root rot, so I almost never cast, and even black, branches and stems (the leaves in groups of 5 or 6 growing from a pole, like a flower in autumn). I re-pot into a larger container and I cut all the branches () is soft and black. Even after a decline in pots and branches of evil, does not receive more branches .... blackened and the leaves fall. This is my second, so I think to really alive! Ideas? Of course I'm a bit lost, and time is running out for this poor plant. Thank you!
