Paramount Plus promotion fiasco

Judging from some of the posts I've read here and else were it seems my experience has played out with several other upset T-mobile customers as well.  I subscribed to the Paramount Plus deal a couple of days ago only to be sent an email confirmation from Paramount with the following conflicting verbage:

"Your payment method will be billed $4.99 on a recurring basis when your trial expires on Jan 2, 2022. Charges will apply if you do not cancel before Jan 2, 2022 except if you have a discount that covers the entire cost of a subscription, then you must cancel before the expiration of that discount to avoid charges. Taxes applicable in certain states.

*Coupon: 100% off for 12 months has been applied. For your updated billing amount and trial ending date, please visit your account page."

So, of course, at first glance it literally gives me less than a week to cancel or my credit card will be billed.  Not even the standard (non T-mobile) 30 day Paramount free trial.   Anyways, so the bottom of the email says a coupon for 12 months free has been applied and that my Paramount Plus account page will reflect that. 

Great awesome, right?!  I should be all set….Nope.  On my Paramount account page it still stated the same thing; that if I do not cancel before Jan 2, 2022 my credit card will be billed.   So, I did the only thing that makes sense in order to avoid having my credit card charged for this shady crap, canceled my subscription and tried to re-apply for the promotion after speaking with Paramount Plus support about my issue.  No such luck, they said to contact T-Mobile so they can give me a new coupon code.   That's where I sit now - waiting for a proper answer from T-Mobile instead of vague voicemails stating my issue is resolved when it isn't.  They have yet to provide me a new coupon code when I have read else where others were given one to re-apply.  I have been with T-mobile for over 15 years and this is the first time their customer service has really disappointed me and made me think twice of staying with them anymore.
