Welcome to limbo.
It's not limbo.
Limbo is a situation where you have no choice about whether you stay there or not. Everyone complaining has at least one option that would get them out of the situation. And they don't have to wait for somebody else to intervene.
It's hardly pressuring Vodafone as long as people are happy to complain but are not actually putting themselves in a better place.
P.S.
If I was in the same situation then my two main options would be to leave or get monetary restitution that I am happy with. The frustration of having an incompetent connection would have a far worse impact on my life paying a break/termination fee of a few hundred dollars. That is true, even if I don't have that money spare.
I call bad connections "incompetent" because they are "inadequate for or unsuited to a particular purpose or application".
I've already told Vodafone that I am planning to leave when fibre is available next year. But that doesn't mean that I will definitely leave in a year. I will make a decision based on what works out best for my family at that time.
