Internet Speeds upgraded to 1 gig up and 1 gig down, shipped a new XB10 with the wrong power adapter

I received and email stating that my internet service was upgraded on 8/5/26. It had a link to order a new XB10 modem which I did and I received it a few days later but it had the wrong power adapter in the sealed box. I called and was told to visit the nearest store to have it replaced that they had multiple in stock. They had none.

I went home and called customer service and they checked another store 45 minutes away and said they had them in stock. I drove to the second store and they had none in stock but would order me one. I waited again... After a few weeks and no modem, I called customer service again and was told they were placing an order for another modem and I would receive it in a few days. It too never arrived.

I called again and they said they would place another order for a new modem and I would receive it in a few more days. Today, I received it and it was a XB8 modem which I already have.

So I called again and wasted another hour and half of my time to try and get the correct modem shipped. I had it escalated to a supervisor who was also no help. He suggested going back to the store and putting my name on a list.

It's been over a month and I still do not have a new modem. How do I get one?? I've spent hours on the phone with customer service and hours in the car driving to different stores? Can anyone at Xfinity help me?
