No internet - very poor technical support

We have been out of ADSL service since last week Tuesday 30 June. We have called your technical support every single day. We have spoken to at least 20 different people and still we have no connection. And all your agents have different stories about what the problem might be. Finally after more then a week a technician came by our house, our line is fine and our router is perfectly fine. The problem must be the password according to the technician. But why is nobody from technical support able to help us? My husband has been phoning with technical support for over an hour now, AGAIN. This is totally unacceptable! We are paying for a very expensive service which we are clearly not receiving. We work from home, which is also impossible at the moment. This situation needs to get sorted asap.
