Why am I being declined all the time (needing improvement of Value Proposition Articulation?)

Hi, I'm wondering if someone could please offer me a hand of help because I'm literally at the bottom of my hopes. No matter what I say and how I say, the result is always being declined like "we aren't interested" or "we already have this" or "situation is not that bad" etc. I'm approaching worldwide public companies (enterprises) and my main focus are, due to the nature of the value, Chief Financial Officers and/or their first level assistants. Sometimes I provide my message to CFO directly but usually I provide it to assistant to pass it to CFO. I'm involved to the lending firm and I'm looking to get new borrowers so "our" underwriting team may either approve or decline their request but everyone is telling me they are not interested or they have good liquidity position. Sometimes I provide my message in a form of email content, sometimes in a form of self recorded video speech presentation where I upload the video of me speaking to Google Drive and send them the link with two clarification files in attachment. I can't just schedule the call with someone here on Clarity because payment in advance is required but I'm paid (never been yet because of no success yet) negligibly small amount of the deal only if they really request additional capital (no one has done it yet) and if our firm approves it. We are talking about the potential of very large amounts in the nonrecourse loan and I'm approaching giant public companies with extreme numbers in their revenue. Would anyone please be willing to discuss this with me further and to check my communication (pitches / approaches) to see what I'm doing so much wrong: 100% rejection rate? I'm looking for entrepreneurship C board of directors communication (value) expert... I don't sell anything! There is no marketing involved but it's about putting the massive value to their business and making sure they do NOT use their own capital for whatever purpose (goal).
