Pathetic Service and nonexistent customer service

So I've been asking for help from the contact center for many months now as the so called unlimited service is only available for 4 minutes per day but i still have to pay the full price....

Hi Pam

Hope you are well.

Unfortunately in your area we are unable to assist with your issues.

You can opt for a cancellation or use services as they are.

I do apologize for the inconvenience.

So please tell is this not breach of agreement at its highest!! How is this appropriate or even legal ????
