Fix my line

I'm so disappointed in their communication, I haven't had connection in 3 weeks. And everytime I want to talk about it,they don't answer and at the moment I'm considering a cancellation but they told me I have to wait for a month to do that. I'm asking myself how am I going to wait for a month if I don't have fibre?... Do you still require a payment if I'm not interested and I want to cancel?
