Seems to be the same problem as many other people, our installation date has now been delayed by almost two months and we've had over 20 missed appointments. The app has said they will turn up every day for the last two weeks. Even after this the customer service line still insists every day that today they really are turning up. And then of course they don't, the appointment rolls over to the next day and customer service insists that this is the new guaranteed date and they will definitely turn up.
What can we do? The final installation date keeps getting delayed because the pre-installation hasn't been carried out. Has anyone had any success resolving this?
