Just to add to this, it sounds like OP didn't contact Affirm until after they already started the charge back. I definitely don't think it is appropriate to do a charge back before contacting the vendor that got the payment, which is Affirm.

My credit card won't even let me initiate a chargeback until I've contacted the retailer.

OP contacted the retailer according to the story. Affirm is not a retailer.

They are the party receiving the chargeback though. It's just usually the retailer that you pay directly.

Cards that are higher up in benefits and fees in the US will.
