T-Mobile breaking promises to seniors who were offered price-lock guarantee for life on 55+ rate plans

I had the Magenta 55+ with the "price lock guarantee" as well. Signed up in December 2021. One line was unlimited talk text and data. One line was talk and text only. I was very satisfied with my service until we got the messages that our bill would be going up. I have gotten FOUR different stories from Four different reps and all conflict.

1) first call -  I was told that one of the lines, the talk, text, data line was priced lock guaranteed, and the other was not. I know it was a price lock guarantee on both that I was initially given. I had my notes from the call  2 1/2 years ago where I asked them three or four times to confirm, and they did. The representative during my first call a few days ago suggested to keep the bill down to change to the essentials plan, as my usage was not that high anyway. I stupidly changed. I then made a comment on T Mobile site on Facebook and they asked me to chat. So I did.

2. Chat number one - in the chat, I was told that the first representative was wrong, and that the line that went up was the talk and text only line. He assured me that the magenta 55 line was price lock line. He changed me back to my prior plan and assured me there was no problem with doing so, everything would stay the same.
3. then I get a text message about when my bill would be drafted on auto pay and it was $25 or so more than it was supposed to be so I had to call and speak to a third person. The third person assured me that the second person was wrong and that the first person was correct in which line was supposed to have been price locked. Then they tell me that NONE of the lines were ever price locked. The bill did get adjusted back where they took the $25 off and the bill was only five dollars more  not $30 more. However, the fact remains that the bill went up. Again, where is their price lock guarantee? 
   4.  Just now, I saw a comment on their Facebook page about the same issue, so I made a comment. Of course they wanted to chat. I know it's going to do no good, but I'm in the middle of one now. This person tells me that the magenta 55 with the data is on the price lock.  See update below.

so what is it? I have four different answers or opinions which all conflict. I don't know what T Mobile is doing besides lying to customers. The initial representatives when I switch to T-Mobile confirm the price lock, which is now somehow gone. Are they lying Just to sign people up? is it because T Mobile is purchasing another company and they want more money? 
 

5.  And now, the current chat - Rep tells me initially that her first info given to me in this chat  is incorrect in that only one Line is going up, but NOW - same chat - so sorry,  BOTH lines are going up!!!!!, The other three said only one line was. So this is story number FOUR !!!!!!!!!!!!!!!!!!!!!

Made a Facebook comment just now, and again, they want to "chat", or for me to IM them my phone number. As if I will get any satisfaction at all.  They are saying what they want to keep people in a conflicting circle of lies.

They do not know their butt from a hole in the ground, or they are just instructed to say anything at all to get rid of dealing with the customer.

I don't know where to turn because you get a different story each time. All I know is it's a bunch of lies.

T MOBILE.     YOU SHOULD BE ASHAMED !!!!!!!!!!!!  But I know you are not.

PATHETIC.
