Shocking service Firestream Broadband Service Provider

In December i signed up with firestream. after receiving my router it would not connect to my phone via WiFi it was saying that the password was incorrect. I researched on the internet and whatever i tried would not work. Mark form support at Firestream said it was not their problem if my device did not work. When i tried to connect my wife's phone same problem my laptop my iPad and my TV nothing will connect with the router. when you try and contact them the person you are trying to reach is not available, when you get hold of Mark it seems like he is the only person there he talks down to you like you the village idiot no respect. I have given them notice but Mark is not releasing me form firestream so i cannot connect to any other service provider. I told him on Monday to send me a statement on what i owe in the account I will pay him immediately no response, with the WiFi mot working we have not had TV for over a month as i stream off the net. Dont ever use this service provider they are terrible and just don't care about the individual.
