Fiberless and getting in the middle of service provider's issues

Between paying for cool ideas as an isp via Vuma Mitchell's Fiber I'm sad to say that I'm still not connected since the end of August It's nearly November... Daily feedback from Cool Ideas with Mitchells Fiber not getting back... It's super annoying... Who do you Blame when the I e company is blaming the other. It's apparently an address issue. Where to from here!!!
