Terrible service, no phone line for 3 weeks.

Really terrible service. I have been waiting for over 3 weeks to get my internet and phone line up and running. I have phoned several times and nothing is getting done.<br> <br> After phoning in i asked for someone to come fix the line they said they will try. Then on Thursday the guy rocks up when im not at home and phones and says he is outside. I said i am out can you come back Monday and he said yes. Now he is saying he cant come today.<br> <br> This is **** service and i am not paying for these 3 weeks that i have been down. PLEASE CAN SOMEONE SORT THIS OUT ASAP!!!
