No Service - only Bills

I logged a local speed issue on the 01/04, with evidence that the Vuma line speed hand-off is 100/100, and when I get to their network I get 50/50.

The reply is to ask me to disconnect everything from my network and then do it (even though the Vuma test was 100/100) - the blame goes to my network.

On the 02/04 added more evidence, no reply. On the 03/03 asked the accounts department what penalties I would have if I cancelled due to their non-response. On the 04/04 I inform them to release my line to Cool Ideas - as they are just flat out ignoring me. Here I got an immediate response "Only at the end of May when it's cancelled."

So, I have a slow line that they are not interested in fixing, but can't go to somewhere else where I will get service. So I am stuck for 2 months on half the service I am paying for?
