hello - I bought an item with return and would like to send this back because it doesn't fit. return started - shipping QR code received - item packed ... and it keeps showing the message that the QR code is invalid. screenshot, printout, etc. none of it works ... what can I do?

@down74 I have gladly added the tracking number. If you haven't received a refund by tomorrow, please let us know and get back to us here again. I wish you a lovely evening. Best regards Selina
