Simple Choice plan change

Well, I thought I was good but I guess not. After Tmobile increased our rate $5 per line back in April - but left us on our Simple Choice plan I thought I was good, but then today I logged in to pay my bill and it increased again due to them moving us to the new Experience More with Appreciation Savings plan....This might be the last straw for us as Tmobile has slowly gone from the value/bargain option in the to what seems like the most expensive option nowadays.
