Impossible to book an installation. Website for bookings down since 2 weeks and not getting fix. They do not respond to emails, and are pretty unreachable on the phone. You can wait one hour on the phone to then have your call disconnected and no one calling you back. The most awful customer service I have ever seen. Although Three is pretty bad as well, but I would say Hyperoptic is definitely worse. The problem is all internet providers in the UK seem to have agreements between to keep their services extermely poor and save on costs. So, ironically while this is London one of the first cities in the world, it's impossible to get a decent internet connection no matter which provider you chose.
