ah HA!!! LOL, this has some cool shit in it... I have to read the rest but LOL if this is true:
Well, what CAN you do about it? YOU NEED TO ISSUE A COMMERCIAL AFFIDAVIT. You don't have to title it that, but that's what it is. You can assert in your affidavit, "I have never been presented with any sworn affidavits that would provide validity to your assessment. It is my best and considered judgment that no such paperwork or affidavit exists." At the end of this document, you put demands on them. They must be implicit and then you state, "Should you consider my position in error . . ."
You know what they have to do now, don't you? They must come back with an affidavit which rebuts your affidavit point for point, which means they have to provide the paper work with the real assessment, the true bill in commerce, the real sworn affidavits that would make their assessment or claims against you valid.
No agent or attorney of a fictitious entity can sign an affidavit for the corporation. How can they swear as fact that the corporation has done or not done ANYTHING? They do not have the standing. They cannot and never will provide you with this. This means your affidavit stands as truth in commerce.
