No wifi connection ,poor customer service!

I got my wifi installation on the 9th of November, needless to say that was the only day I had coverage. I have logged tickets on their website and they have just closed them.without the issue being resolved, I've called and can never get through to anyone. At 08.47 I send them.a message via Facebook they responded at 10.05 and immediately closed the chat advising me to use the very same useless website I've been logging complaints on!
