My speed has dropped from around 8-10mb to 0.4mb

[Scubbie]

Whilst it may now be Saturday morning, I would be tempted to call again as waiting up to 80 hours (i.e. 3 days & another 8 hours) is not acceptable.

Be nice on the phone and hopefully you will get someone to look at the issue sooner.

If there is a fault on the line, it needs logged to Openreach. Call back and confirm the fault has been logged. If so, 48 hours resolution is the typical time.

I would not risk them making a mess of it. 11Mb is quite a good speed for your attenuation and the low noise margin shows you are getting as much as the line is capable of.
