Despite the rules about paying back maintenance etc, I am currently disillusioned enough to be considering cancelling maintenance.

I am wondering what I can still do if my maintenance is not current?

Do I still have access here for example?

If service packs are issued for the version I have paid for, do I still get them? or am I locked to the service pack as well as the version?

Where is a good place to find answers to these questions, when I no longer trust my VAR?
