I bought some electronics, turned out it was a scammy company. After six weeks, nothing shipped, merchant agreed to refund me. Asked card company (Cash/Square/Block) for a chargeback. Week later merchant ships something, FedEx fails to deliver and it gets returned to merchant.
3 months later Square asks me for all documentation. I give it to them. They say I can't have a refund as the package was delivered. I tell them "yes, delivered back to the merchant". They say "sorry, our policy is that if it was delivered somewhere then we won't do a chargeback. I know that's not the outcome you wanted." Then they terminated my account. LOL
