ADSL line problems since installation

Had my telephone and ADSL line installed yesterday. Since the internet came up it is hardly usable. I can hardly load a page and I have a 2meg line. The internet also keeps disconnecting.<br> <br> All I get told is congestion on the exchange and no one can help me.<br> <br> Telkom sales team puts me through to support and vise versa. I am not even allowed logging a fault as apparently my account has not been activated and have no phone number ( *** )<br> <br> Please help me.
