But the fact the jomsocial is working fine, I am not sure you looked the wrong database or not, simply just provide me the phpmyadmin access, I will look it directly.
Here are screenshots of my database and all of the tables in it.
Once again, I installed JomSocial originally on my own. ~60 tables JOS_COMMUNITY_... were created in my database.
JomSocial was not working however, so I unistalled JomSocial and dropped all the tables like so:

I could not find any docs specific to Joomla 3, but I assumed it was the same procedure.
I posted on these support forums and waited for the weekend to pass.
After the weekend had passed, I noticed that someone from your support team had logged in and installed JomSocial for me.
This time the JomSocial worked properly but there are no _COMMUNITY tables in my database where they were last time.
