I do not think we get bills You can ask yourself what makes a piece of paper into a bill? I would think it has to contain an unconditional order to pay (ordering addressee to pay) Court order might qualify, but doubt if the statements from limited liability companies are bills. The they say it is an invoice or a demand In my opinion Bill of exchange act is one jurisdiction, but "statements" we receive are are from some other Jurisdiction, hence the bill of exchanges act might not apply; To understand it easier, it appears there is United states of America, there is United States corporation which has a branch of a state of California and then there is Republic of California, most people identify themselves as citizens of United States (corporation), but try to bring up rules which pertain to United States of America or Republic of California. Something similar might be going on with Bills of Exchange Act as well. You can simply ask them: " is that a bill, invoice or demand? Are you ordering, invoicing or demanding me to pay?" if they can not confirm it...just say: "nobody asked, demanded, ordered me to pay...i do not know what do you want from me." They exploit us look up modern slavery act section 1 and 3 (5), there is no fraud or extortion, we are volunteers.
