Thanks, got it. Do you know if asking to sign papers is standard procedure? I thought it was only some voice questions

I believe a lot of companies do it, it'll most likely just state that you're confirming you haven't received your package. I've never experienced it myself though, I've heard they're sometimes legally binding. If your refund has been finalised then you don't have to do anything else, simply ignore the driver.
