Thanks so much for popping back - I am sorry that you've had some issues getting the help you needed when you called; Thanks so much for checking another handset for us - I can see that we have no known area issues listed in your area and all other checks have been done so I have gone ahead and booked you a technician.
You can check the date and time of this visit via your online account - if you need to change or cancel it, you can do it via your account also. If you have any issues locating the timeslot, please do pop back and let us know.
Thanks for updating us about this, I am sorry you've had this poor experience one after another!
I can see one of my colleagues on the Forums, Lisa_C, has picked up your other post and is dealing with your issue. I can see she has booked another tech visit, she will take care of you if you need anything else.
Please let us know how the next technician visit goes.
