Just my two cents here...
Your robots.txt file is way messed up. You have cross domain disallows in it.
Let me show you...
The above on the domain sitecode.ir does nothing for you... you should remove those lines from your robots.txt
In addition your sitemaps are not done correctly. You should have a sitemap of sitemaps. The way you have it is wrong.
here is what you should be doing.. you life will be simpler and some of your indexing issues will
The following example shows a sitemap index in XML format that lists two sitemaps:
<?xml version="1.0" encoding="UTF-8"?>

Edited to add
In addition to the above.. some of those urls in your robots.txt are infected and set off my
security software.. Those sites could also have a negative impact on your site.
