Fibrestream disconnected internet service

Have been disconnected from internet since last week Wednesday. Fibresteam aren’t answering calls and replying to emails. When you get lucky enough to get through to them they promice to call you back within an hour; its 5 hours later and still nothing. They dont even have the decency to give customers any communication. When I called them last Friday they had an automated voice recording that they had their end year function. Worst-case of customer service I have experienced, they just don't care.
