Estafa Case? Fake Trust Receipt

Ive got the trust receipt and i also found some partial payment receipts which include a reference to the trust receipt(receipt number) and penalties for late payment(of the loan). the date on these partial payments are dated before the due date of the trust receipt.

there is no mention on the trust receipt of partial payments so im hoping this would help toward prooving there was no items involved in our deal, since why would penalties incurr when the date on the receipt has not yet passed, and why are partial payments been made(which maybe a little circumstantial i know) but they look more like precalculated payments rather then someone paying an amount this week  and then a different amount the week later just to pay what they can while they have some extra cash

but still is there anything else i could be doing to try and invalidate the trust receipt.
just so estafa cannot be filled

The Trust receipts law is quite strict. It is malum prohibitum, mere failure to deliver payments or return the goods which were not sold will make her criminally liable unless she could prove that what she signed was not a Trust Receipt but some other contract.
