Returned equipment after canceling services

Hi,

I canceled all xfinity services a couple weeks ago and returned the xfinity modem to my local xfinity store in person on Oct. 3rd, but I got an automated call that said I still need to return it. I already did in person, so I have nothing left to return. I've already given everything back and it says I should be getting a refund of $84 since they made me pay for a month after I canceled services.

I just want to check into this and have the equipment marked as returned since I literally handed it to an xfinity employee myself almost 2 weeks ago. I asked for a receipt at the time since every other company has always given me a receipt when turning in equipment, but the xfinity employee said they don't give receipts and that a receipt wouldn't help anyway since it's not scanned as returned until they ship it back. This was a huge red flag for me since I've already been scammed by this company on more than one occasion since I signed up for services, and lo and behold I get a phone call a week and a half later telling me I haven't returned it. Not surprised at all.

I would appreciate help with this and getting it properly marked as returned. I returned it to the Spokane Valley, WA xfinity store on October 3rd, 2025. Please help me proceed with having the modem/router marked as returned since I returned it directly in store on October 3rd. I have to take time off work just to go into the xfinity store because the hours aren't great, and it's ridiculous what I had to go through to return it just to be told that I didn't.

Thank you for any help.
