2G free phone replacement

Thank you for the follow-up question.  I printed out the information from the T-Mobile website (https://www.t-mobile.com/support/coverage/2g-retirement) and took it to the T-Mobile stores (three different company stores).  The employees in each store were unfamiliar with this T-Mobile website page.  When they researched this issue on the T-Mobile employee intranet on their handheld tablets, I was informed that T-Mobile should have contacted us by mail or text message.  One of our two 2G phones did receive a text message advising us that T-Mobile is ending its 2G network.  However, when I showed the text message to the store associate, I was informed that it is not the "correct" text message for this offer.  Apparently, there are different text messages sent to different customers.  I have also tried calling the T-Mobile 1-800 customer service number a few times, but they informed me that I need to go to a T-Mobile store for assistance.  Both of our 2G phones are T-Mobile branded phones that have always been on the T-Mobile network.  We have been the only owners of these two phones, so I am not sure why T-Mobile would not have a record of this.  With the T-Mobile stores unable to help and customer service call center sending us back to the T-Mobile stores for assistance, I am not sure what the next step is.
