New phone sent to old address

I ordered a new phone via customer service and they assured me that my address was being updated on the backend. I got the order confirmation and it had our OLD ADDRESS. We moved 2 years ago. We’ve had internet, cable and phones at this address for TWO YEARS. I contacted customer service today to hopefully get the UPS delivery updated to my current address. Rep opens a ticket and tells me that I need to upload proof that I live in the new address (THAT WE HAVE HAD XFINITY SERVICE AT FOR 2 YEARS). And the tracking number (FOR THE PHONE THAT XFINITY SHIPPED ME). Please help me with this disaster. I’m so close to cancelling all of our services over horrible customer service.
