Wifi 7 gateway

I recently signed up for your Internet service. When I signed up I was told my service included a wifi 7 gateway. I did not receive a wifi 7 gateway. I received a wifi 6 gateway. I texted the Xfinity representative who sold me the plan and they instructed me to use a digital assistant. That assistant eventually had someone call me. The person I talked to did not understand my issue and could not provide me with a solution. They said that someone else would call me within 24hrs. That was on a Thursday afternoon. It is now Monday evening and no one has called. I would should have the gateway 7 you agreed to give me as promised when I agreed to purchase your service.
