Waited in all day for engineer and they didn't turn up. Rang the company only to find engineer had come at 4, while I was home, took a photo of my door and not bothered to ring the bell. I know the bell works because I checked it while on the phone to the company. Not only did they not ring my bell nobody rang me despite me giving them my contact number. I rescheduled the appointment and this time they turned up while I was out although I had said on the phone while rescheduling that I'd be out before 3 and they said that was ok and they will request the engineer come after 3. They came at one. They give you a time slot of 1-6, I don't think 3-6 is a ridiculous limitation especially since the first time they didn't even bother to use the bell! If I had been told over the phone it was not possible to amend the time slot I would have made sure someone was in. I need the Internet for my work and this has really inconvenienced me.
