My internet has been slow and unreliable since Monday, I had an engineer out to look at it today, he replaced a damaged cable and left and now it doesn't work at all

I need the internet for work so I've had to use mobile data. And I only have a limited amount of that so I'm having to avoid anything bandwidth heavy in my free time. Can't watch streams can't watch videos can't do fuck all

Currently waiting with bated breath to find out how soon the engineer can come back
