Assist me FFS

On Monday i got my land line installed. I want to get adsl THROUGH A DIFFERENT SUPPLIER but because you are the only ones that can activate landline i have to go through you. I am fed up!!! Today is friday and my Service Provider cant activate internet because my line is suspended. I phoned call centre everyday.... My line is connected to another person and has been suspended. No luck at call centre as they keep telling me tomorrow. How difficult is it to activate a line. I am so tired of fighting everyday i am done. I cant believe its such a struggle just to get my land line activated.... You can forget about me taking adsl through you. I cant even find a complaint number !!!!! Get it together and assist. Dont just say you are emailing the technician.... I dont care i want my line activated NOW!!!!! The land line is ***. My surname is van Buuren. You connected me through an existing number amd now i must pay the price. Why do i even complain to a monopoly. If there is any other company that can activate a landline o would go there in a heart beat.
