Intermittent broadband in S6

I had a few channels not working on my 360 and a technician came and left me with no TV or broadband. The TV came back by itself after a local fault message appeared in the app, but a different engineer restored my broadband Friday afternoon (and needed to go to the street cabinet to fix it). Saturday morning I noticed intermittant loss of broadband and I booked another engineer via the app, but cancelled Monday morning after the fault seemed to have gone.THe fault returned but even though the service status stated there was no problem, when I tried to get the app to check my equipment it told me there was an intermittant fault and to try again to book an engineer in 24 hrs. 24hrs later it still says try later and I caled 151 and was told the same thing, but I am convinced it is a fault unique to me. I have a feeling that in 24hrs it will still say try again in 24hrs. Can I override the system and get someone to come and fix it
