I Feel Cheated and Deceived with T-Mobile lies and false advertisement.

I'll pile on and note I had a very deceiving and negative experience with TMobile online Support/Sales.  I spent almost 4 hours in a chat session and on the phone with them trying to get an equipment upgrade as they advertised up to $1000 off of an upgrade to a Samsung S24 Ultra.  I currently have a Samsung S21 Ultra.  The offer noted that the upgrade was available at that level with an upgrade of a plan to the Go5GPlus plan, so I went through the process of upgradinding first and then with the same sales rep (Danilo) started the upgrade process for the device, ensuring along the way in my chat session that I was on the right plan, that the previous warranty claim that I just closed on my S21 Ultra wouldn't impact the offer (I had a screen replaced and the phone is in mint condition), all with assurances I 'could believe the deal'.  Well, after finishing the upgrade requests and signing all of the agreements, I receive a text message stating that the trade in value of my S21 Ultra was $175.00.  What deceptive advertising!  I will be cancelling the upgrade and then will proceed to find another carrier as soon as the upgrade credits from almost 2 years ago on my spouses phone are complete.
