What do I do if the shop manager initiially says she can give a receipt for XB10 return but after she processes it says she cannot

Thanks for reaching out through the Xfinity Forums, @TambourineMan. I can understand why that would be concerning. If the equipment was successfully removed from your account, the photo showing no equipment listed may help as documentation. Have you received any email confirmation or seen the return reflected in your online account yet? That can help verify the return was processed successfully.
