Since 24 November 2022 I've had no reception on my router

Since 24 November 2022 I've had no reception on my router. After dozens of calls and emails of complaints to them it was n9t fixed. Early January I told them to can do sim since they do not provide me with their service. I've received an email informing them the service will be cancelled. This morning I see they want to debit my bank account for monthly fees. Why should I pay if a service was not delivered there is no signal at my house they have not fixed it since last year. They are trying to make money out of people . They told me service will be cancelled. Their operators are poor they let you hold on up to 10 minutes they make empty promises. I used them for a few years but since November I will not use them again
