$250 Virtual Prepaid Mastercard

On 4/27/23 I went to https://promotions.t-mobile.com/ to redeem a $250 Virtual Prepaid Mastercard.

A few hours ago I found Welcome to T-Mobile paper I saved and a link to 2 emails I received from T-Mobile.

One shows a submission date of 5/6/23 and a tracking #

other shows a tracking ID and a pin # dated 4/19/2023

Days between 4/27/23 and today 08/09/2023 is fast approaching 4 months.

Where is redemption?
