This is kind of OP's fault, right? I don't think it was appropriate to initiate a charge back on a payment to affirm since they provided their service to OP, that is they already paid for whatever OP was buying. I have a feeling that timing between OP opening the chargeback and the shipping of the item was actually coincidental. I'd think if you paid affirm and the merchant hadn't shipped the item, then your recourse…
Yikes, I can’t believe all the comments blaming OP. It was clearly the retailer in breach of Affirm’s terms, not OP. Charge backs also have a limited window to claim - I can’t see anything that was done wrong here by OP. Yes, OP could’ve attempted to resolve with affirm up front, but why should that be necessary?
That window generally starts counting down once the original transaction has completed in it’s entirety, which means you’ve received the goods (until you get the goods or services only one half of the transaction has completed).
If the merchant doesn’t deliver, then there is no limit on the chargeback period, assuming you’ve made a reasonable attempt to chase the merchant and got nowhere.
