My Apple Store App on my iPhone has a problem. It will not let me make a purchase using my Apple Card with monthly installments. Full price is fine. I was told that I could buy it full price and then call to convert to monthly installments. So, I pre order the iPhone 14 Pro Max 512GB on pre order day and pay full price. Apple told me that they couldn't convert it to monthly installments, but Apple Card could. When the charge hit, I converted it. Then, I starting thinking that I want the 1TB model. So, on launch day, I find inventory at my local Apple Store and I order it using Safari on the Mac with monthly installments. I pick up the pre ordered iPhone from UPS yesterday and immediately go the Apple Store to return the 512GB iPhone and pick up the one I just ordered. I wanted to make sure that the monthly installments on the iPhone I pre ordered would be erased as I returned it. The Apple people didn't know, but when I talked with an Apple Card person yesterday, I was told that the amount would go to available balance and it wouldn't be a credit. Guess what. A credit showed up today on my account. I complained to Apple Card. It went up the chain of command and is now a 'complaint' and I should hear from them within 10 days. I have a few monthly installments. I should not have to pay a monthly installment on a product that I do not own.
