I received a promotion to get 3rd line for free. I accepted it and received just fine. After 25 months. It started to charge me for it. I have been calling everymonth and receive adjustments with promises to fix the problem. The problem stil persist and called today and the Agent denied any promotions and told me there is no promotions on this line and that T-Mobile will not honer the promotion I received with Sprint. I asked to talk to a supervisor and the agent told me, he is not going to help or change anything. It is frustrating and extremely stressful 

I am experiencing something similar.  I have had 3rd line free since June 2020, suddenly it has fallen off my account.  I have called numerous times about this but no one can explain why.  A few representatives have added the promo back to my account but it falls off each night.  Going into a T-Mobile store has proven useless, as I was told they're only there for sales.  I believe Magenta plans are being obsoleted and this is T-Mobile's way of forcing customers into the Go5G plans which are slightly higher.  If that's the case, just say it.  It is clear they are unable to reactivate that promo for my account and I refuse to pay an additional $30 per month for something I am supposed to get for "free".  I will have to find time to send an email to corporate on Friday.  I've been calling since June 9th trying to get this resolved and I am tired.
