No Landline for 6 weeks

<p>Our landline has been out of action for 6 weeks or more now, without anyone coming to see it. I have reported the problem multiple times without any joy. I even had to move to LTE just so that we could get internet going again. </p> <p>Seems like each time I report the problem, they just reset the fault date. I have even tried the online assistance which keeps crashing and hasn't been helpful at all.Worst of all, is that we are still being charged for this service we cannot use. How can we escalate this?</p>
