IMDb doesn't value it's users and keeps data INCORRECT

I tried several times to get them (employees) work on the problem with "Cosmos: Possible worlds" page, but they say it's correct because they don't want to bother with it. It says the series has ZERO episodes and we can't rate or remove rating for that title, and according to IMDb - it is like it has to be! The nerve! 

Also, they keep on refusing changing genre of several titles - all of them are actual horror movies, but they refuse to add it!!! How about keeping your data correct? The problem is with these titles:

1. Don't look now (1973)

2. The Cube (1997)

3. The Ninth gate (1999)

4. Joy ride (2001)

5. Triangle (2009)

6. Frozen (2010)

Address these two problems accordingly and in timely manner.
