Help! Professor/Advisor Refuses to Publish Any of His Students' Research
First, this is not an unusual situation.  What is unusual here is your interpretation of the situation.  

When you have a problem with someone's behavior, it is wise to look for incompetence instead of malice.  It's highly likely the professor intended to keep his promises but failed to do so.  You have given us no evidence otherwise.  Professors commonly break promises to submit papers.  Some of them do so over and over without realizing there is a pattern.

Your best strategy here is to politely remind the professor of the missed deadline and press for a new deadline.  Repeat this process as many times as is needed.
