When will CRM be updated? It has been 4 years and the same bugs

Hello, I have been a zoho customer for around 4 years.   The CRM interface for leads has never been updated.  It has the same limitations and the same bugs. 
There is no way to reach a human being that I can find.  No Chat, No email.    Are you ever going to improve what you offer or should I find a new product?

Right now I cannot add a user even though I just paid to upgrade my subscription.  I cannot edit the email of an old inactive user to assign it to a new user.   I cannot add the ROLE even though pop up windows are not blocked. 

You are wasting my time which is worth over $100 an hour on something very stupid and lame.
