Phones delivered to the wrong address and no one can resolve this issue.

I am now on my 5th call with Xfinity and no one can solve this issue.

Decided to switch to xfinity mobile from ATT and also purchase new phones. On the day before delivery I decided to track and noticed the shipment was going to a city that I had never lived in nor have any affilitation with. 

I called and a case was opened to reroute the order. 

I followed the order only to find it was marked as delivered and sign for at the address that I have no affiliation with. 

Called Xfinity, they said I had to wait 15 days for the ticket to be resolved. Mind you I have already paid for the phones and only have 21 days to send in for the trade-in credit. I was told they changed the ticket from reroute to lost/stolen. 

2 days later nothing, I called them. I was told the original case was already closed. But no one called or communicated anything. So quite possibly I would have been just waiting with no progress at this time. Again a case was opened and I was told that I should receive an email and that I needed to wait. Tick tock....now 6 days, phones are in someone else's hands, who FedEx was supposed to require signature for delivery and said they did...but I am out money and time. I asked them to cancel the order and they said they could not. 

Thus far, every call has been futile.
