changes in channels?

The channels I pay for are no longer coming through., I was not notified that anything has changed. I have tried to find the info on line and it is not available. I have reached out to talk or even chat with a live person and it hasn't happened. Why am I not getting what I pay for? I am really tired of things being so difficult. I should not have to work so hard to get help with something I pay for !!!!!!!
