Precio Fijo

So, I just received a text.  My Magenta Unlimited 55 price lock guarantee is not being honored.  I was told by a representative the plan featues would not change, but the price now can; I was also told my plan is retired when I said it was now discontinued.  (I am not sure why that word was being used.)     Additionally, the page that lists all the information about the Magenta Unlimited 55 plan features is no longer available on the website.  I asked a service representative to email or text me a copy of the features of the plan so I can comparison shop with other plans, both in and out of the TMobile sphere, but she said she could not send it; she could only talk to me about it.   I am realizing a  $12 increase which equates to a 15% hike. I am feeling duped. I found multiple articles on the internet talking about the price lock guarantee on the Magenta Unlimited 55 plan.  Way to support your senior customers, TMobile!
