There's every chance the issue is affecting just yourself and there's nothing you can really do except wait for an engineer. It might be affecting a couple of people but not enough for the system to flag an area fault (imagine it affecting 2 people on your street out of 30, the system usually triggers off of 10%), however if someone has a tech booked out before yours, it could get fixed earlier. Long shot though.

In short, there's almost nothing you can do except wait for the tech.
