Connection intermittent for 3+ weeks because ‘known issue in the area’

My connection has been intermittent (read: pretty much useless for work or streaming TV without issues) for 3+ weeks now. Whenever I log in and check broadband issues, it says that there’s a know issue in the area but that the root cause has been found. It also lists that an engineer is planned to fix it. I subscribe for notifications and after a few days I always get a message saying the an engineer is now fixing the issue, followed by a message that it’s fixed. Then, about 1h later, the same issue reoccurs. A few hours later, there’s then another ‘known issue in the area’ that’s showing when I log into my Virgin account. I spoke to others in the street and they are experiencing the same issue. This patterns has repeated itself 4 times now, and 3 weeks later, my internet connect is still so unstable that I have been forced to go into the office every day to work. I tried to get to speak to a human at Virgin, but that’s just impossible… Can anyone please advise? I’m getting to point where I’m thinking of leaving Virgin especially now that I just got my bill for the full amount despite all the issues!
