marketing contact at Affirm financing for audio equipment

As a sometime seller, Affirm is unattractive as compared to PayPal Credit. A seller gets charged nothing extra if the buyer uses PayPal Credit. However, if the Seller selects Affirm as an option for buyers to use, the Seller will pay minimum 8% on top of any other fees due. So PayPal Credit = zero extra fees. Affirm = additional 8%. Therefore, I don’t use Affirm as a Seller. But I do use PayPal Credit as a buyer. 

It's too bad that the emergence of these companies have made it nearly impossible for a seller to get paid with a check or a bank check. I recall giving and accepting them many times back in the day with no issues, and better yet, no fees!
They're supposed to earn their keep by protecting us in the transaction, but many people, myself included have had problems with them.

The website and phone number lead to dead ends.

They sound really legit...

A dead end?
How so?
