ADSL No Connection, No Support

For the past three weeks I have little or no ADSL at home, I have logged several calls on the site but they get closed with no resolution or anyone fixing it. I phoned call centre over the past three days with no answer and call timing out - today twice I got through I think and hear people talking in background but not to me just to have the phone put down on me after a minute or so. Eventually the third time the same happened but I kept shouting and then a surprised Jose started talking to me...think he thought that I dialled off already so that he could also pretend to have answered and solved a problem...... At least call logged for the 5/6 time and maybe someone will fix but have to wait two days again. Wonder if I will get a credit<br> <br> I can't find any escalation route, no contact numbers nothing - just the call centre. and they put the phone down on me before I can even talk.This is absurd I can't even find a number to cancel the service
