Getting Paid from Pre-Settlement Funding

Any one have ideas on how to collect from this New York Firm Pre-Settlement Funding? I had to make two trips out to get documents signed for this Maria Pacifico. First they claimed the check was sent but never was. Then she offered to pay me with a Amazon Card.

State of Florida BBB does not handle business disputes. Looked into here as 123 LumpSum was another deadbeat not paying.
