Xfinity 4k - XG1v4 Cable Box Availability

Called Xfinity and asked about the availability of XG1v4 cable boxes at my location (WA state), which has the capability to stream 4k content through Netflix.  Was assured, with repeated confirmations, that they were available to the local service store, would just have to bring in my existing cable box and exchange it.  Bought a nice LG OLED TV, upgraded my Netflix account to receive Ultra HD, and took my box down to the local service center for exchange, per customer service direction.  You can probably guess what happened next - "sorry, we don't have any 4k boxes, don't know when we will".  Anyone else been misled by the Xfinity garbage customer service?  Went online to see what lies they convey on their website regarding this matter, and found this:  https://www.xfinity.com/support/cable-tv/uhd-4k-faqs/   More misleading BS.  Wanted to warn anyone else potentially in the same situation as myself not to believe anything you are told or read about the availability of XG1v4 boxes; go to your service center first to confirm.
