Hi @ChrisAmyPhillip ,
If you play things by the book and keep in discussions with the service provider, it may be possible for you to get the human advisers to sympathize and agree with your assessment that they cannot reliably provide the service which you pay for and they may release you from your contract.
I highly recommend not to unilaterally breach your side of the contract even if you judge the other party is in breach of their end of the contract. If you believe the service provider is in breach of contract, there are proper steps which you may take to remedy that. One such proper step is not to be in breach of contract yourself as the service provider is more properly setup to address breach of contract and would be able to use your breach to release themselves of any blame as they will have proof and you are not properly equipped to prove the service provider is in breach of contract.
I'm sad to hear of the situation you are in as I was in a 24 month contract with another service provider where the signal and performance was less than desired. I recommend to ignore the message that data has run out on an unlimited contract as I believe it refers to the giftable allowance which has run out. I currently see the same message on an Unlimited Data Pass where the giftable 120 GB has been exhausted but obviously I can use further unlimited data up to 600 GB just fine.
