I had a very similar problem a few months back. Openreach had come out to repair a neighbors phone and in the process disconnected mine. As an essential telephone user i.e. I have a care alarm connected to the phone. Talk talk were able to get an engineer back that day. However my good line was then swapped to an inferior faulty one in the process. Talk talk were brilliant and got straight back on to Openreach and got the problem sorted with my phone and broadband the following day. Sadly my neighbors phone was still faulty.
P.S. it may be worth notifying talk talks CEO office of the problem.
