Return label for iphone case keeps renewing after clicking on the link

I returned a case back to Apple a week before the due date, and I didn't know that Apple's software regenerates a new label and new tracking number everytime you click on the "print return label" button. I accidentally did it twice not knowing this, I thought it would always be the same like every other website I use. I also didn't take a photo or get a receipt from UPS unfortunately that was my mistake, and there were no instructions to put any receipt inside the package. The only thing that links that package back to me is my name and address on the label. In my Apple account in the order history, there is no update of my package being sent to Apple because it has been updated with a new label and tracking info, and that new label has never been shipped so it's always saying "Please send this back to Apple".

Before I found out about this, I clicked the "print return label" a third time so I could get the tracking number and look it up, unknowingly creating a brand new label. It's really frustrating, I don't know how I'll be able to explain this over the phone to Apple customer service. There is no way to see any history of return labels printed, that I know of.

Has this happened to anyone else? Do you think I'll still get my refund? I'm very worried now because it was almost $100 and that's a ton of money for me to be out of.
