I honestly suggest this be a case where you find a lawyer in addition to what you've done (just talking to one shouldn't cost you anything). Toyota is stonewalling you and not providing you service, despite evidence proving (that they themselves provided) you did nothing wrong to void the warranty. If the consumer protection bureau is unable to get Toyota to do anything and advocate for you, you need to seek damages here. You have been wronged.
