Lied to about promotion

It seems I am not the only who got scammed with T-Mobile promotions. I went to a Costco location to conduct business with T-mobile.  It was January 2023 and the T-Mobile promotion at that time was "Keep and Switch ($800), 2022 Switch P9 ($200 per line), and Costco 2022 Activate P3($150 per line)" which sound like a good deal, so I switched over three lines.  One line as a Keep and switch because I did not need to replace the phone, I just switch over the service, and the other two was brought in as a Switch P9.  Since the deal happened inside a Costco store, each line was also eligible for the Costco Activate promotion.  I received the 2022 Switch P9 a few weeks later. 

Now the other promotions is a different story, it is now May 25th and still working on the Keep and Switch promotion and the Costco activate.  After Many phone calls with each promising that this time the issue have been identified and fixed, that I must wait 2-4 weeks for the e-card to be activated and I will receive a text to redeem the card.  Every time I call I asked for a tracking ID so I can refer to it when I dont receive a text after the expected time frame. Each time I use the tracking ID, I am told that it is not valid and we have to start the process all over again and again and again.  It is upsetting and it is also the reason why I am posting to hopefully shed light to this SCAM and prevent other people from being victim.
