bad service

On the 27th July I app**** for an adsl line which I had to pay deposit for and the consultant said it would take 10 days to install. Two weeks later go back to let know no one has come out. I was then told they are having a problem that there is no vehicles for the technician to come out but we are scheduled for the 29th July no one came. So I phoned apparently the technician went to the address and no one was there. So I went back to the store and the flat number is wrong. I phoned the call centre but they can't do much then I receive a sms saying on the 1st september it will get done. I thought to myself what ********. I sent the consultant but she never replies to emails. Then I receive another sms saying on 31st July someone will come. I am still waiting.
