I've been referring to all of the OP's posts, not just the one specific situation. He has mentioned having to represent himself, and has gone through the chain up to the local president in previous situations without getting help. What he describes shows a pattern of behavior at the local. Whether his description is accurate or not is obviously unverifiable through this forum, but based on what he described a call to the international is not out of the question:

Teamster Basics - Frequently Asked Questions (FAQ)
"How should I handle complaints about my steward, business agent or local?
Most stewards, business agents and local officers work very hard to provide Teamster members with the best representation possible. But sometimes problems do occur. The best way to resolve complaints is to start as close to the problem as possible. For example, if you have a complaint about your steward, your first call should be to your business agent; if you have a problem with your business agent, you should talk to your local's principal officer.
Business agents generally cover several work sites within the same industry, so he or she will be most aware of what's going on in your workplace and will be familiar with your steward and the issues the steward is facing on a day-to-day basis. The source of your complaint may actually be management. If the business agent is unable to address your concerns, the next call should be to your local. All Teamster locals are autonomous and procedures for dealing with member issues may vary. Some locals may have a staff member assigned to resolving member problems. If that is not the case, ask to speak with your principal officer. You may want to make an appointment or set up a time when you are both free to talk about your complaint.
If your local is unable to resolve the matter, you can call the International Brotherhood of Teamsters Legal Department, (202) 624-6945. Only contact the Legal Department if you have exhausted all local options."
