I am sorry you still haven't manage to get this resolved, I have had a closer look into this and also mailed the AFM of your area and there is still a utilisation issue in your area the ticket number is F008008811 the estimated fix date is 22/07/20 @ 15:00, you have also got high SNR on your end, this is going to cause all the issues you are experiencing.
The technicians are working hard to get this resolved ASAP, I am sorry for any inconvenience caused.
I am really sorry, I know exactly how you feel as I am in a similar boat myself, SNR is signal to noise ration, if this is too high or too low it will effect your services and cause it to be intermittent, the service will work but will remain intermittent until this is resolved.
If it is an underlying utilisation issue then you are deep into unknown territory. Depending on the various factors these sometimes take months or years to rectify. They basically signed up too many subscribers in an area in the past and now the system cannot cope with the incresead usage. Solutions might include VM installing extra capacity, moving people around or just waiting until people leave the area to drop the "utilisation" numbers - so you can appreciate the time constraints. It might be instructive to browse these fora for other perspectives on "utilisation" issues and options.
However, on the brighter side if you have an SNR issue - that might actually be causing the issues and might be more quickly resolvable - but I dont know enough about any "causal" relationship between over-utilisation and SNR - someone more technically qualified might comment soon.
