I've moved into a new apartment, actually moved out for the first time, and Hyperoptic have made this a nightmare. I work from home and am now 2 weeks without internet, forced to hotspot of my own phone at my own expense. I have called and raised complaints to no avail. This is unacceptable. I'm so close to going to the ombudsman at this point.

Has anyone else had this experience? Is there anything I can do? I just need working broadband. My livelihood depends on it.
