Issues returning equipment

I recently moved out of an area covered by Xfinity. I didn’t have time to return my equipement to a store before I moved so I took it with me. Now I can’t seem to be able to generate a return shipping label for me to send the package. Every time I log onto the return equipment page there is never anything listed for me to choose to return. So each time I call and speak to someone and they direct me to go to a USPS store to return the equipment, but then I have the same issue, I don’t have a return label to send.

Now I've been charged 100 dollars for not returning equipment. I want to return the equipment but I can’t unless Xfinity can send me a label. Is there any way I can have a return label emailed to me directly so I don’t have to deal with the finicky website? I don’t typically turn to forums like this, but I’m kind of at my wits end and would like to be done with this process.
