PAYING FOR A SERVICE THAT ISN'T PROVIDED

Beyond frustrated - NO FIBRE since 29 Feb (over a week now). All neighbour's fibre was restored within 2 days of an outage last week & despite calling multiple times a day, still no fibre for us - our complaint has been escalated multiple times, technicians were booked & didn't pitch multiple times (every time making sure someone is home & nobody arrives).... we get the same story of 'escalating' the problem & no results.... how do we get a technician to actually come out & resolve this ?? - we have spent a fortune on extra data, wasted so much time waiting for technicians who dont arrive when booked & the service we pay for simply isn't provided. As polite as the call centre agents are - it's pointless calling as not one person has been able to help us....
