TMobile Says It Doesn't Exist

So, here is the advertisement that was listed in the TMobile Experience store near me. After two conversations with in-store employees, multiple conversations with chat representatives, and a phone call with a business specialist (that ended-up ghosting me through emails) I am beginning to believe that this is a bait-and-switch listing. They all say "there is no Business Unlimited Select" plan. However, one of the in-store employees went in the back for a while when I was first there to make the switch, came out and said that he found it, but the listing was "black" in his system, so he did not have the authorization to sell it. Since then, it has felt like a void of lies and deceit with every agent wanting to sell me something else instead of what I am considering switching for. Has anyone else experienced this? Does anyone out there actually have this plan? Is TMobile watching this sub-reddit and feel like explaining? Ultimately, accidentally coming across this advertisement while I was in the store waiting for a prepaid data card for a mobile hotspot is what made me consider even switching.
