Herotel unstable fibre lines

This has been going on for months now. The ping keeps spiking on my fibre line and keep dropping me from video calls. Everytime someone from Herotel support calls me and updates the router setting and thinks that it will now be sorted. But it never gets sorted. They've replaced my router twice but the actual line is just bad quality.

I get a different support person each time, wasting my time with tests and random ideas but no-one fixes the problem.

If you work from home, or do online gaming and need a stable line, do NOT go with Herotel.
