Assuming it is not your ISP or that the telco is the ISP.

Dont believe them. Tell them to reset the port. Tell them to change the 
pairs. Tell them to switch your line to a different port on the dslam. 
Tell them to put you into a different CO. Tell them to dispatch a 
technician to test your line "at the nid". Get a FTP server with good 
connectivity on the internet and upload/download to it, measuring your 
speed. Show the telco low bandwidth and packet loss. Do some flood 
pinging (carefully).

Test the line with a cheap linksys or netgear or smc or dlink or similar 
"broadband" residential router with ADSL modem (or even software [google 
for raspppoe for windows, linux has pppoe software available as well - 
if thats what your setup uses]).

Spend a few dollars and get ADSL on another phone line if that all does 
not work.

For the money they make off a ADSL line, a Telco is unlikely to do more 
than run the standard automated web testing thingy and say "Everything 
fine here!" and hope you dont call back and cost them more. That makes 
sense. The more support time and expertise expended on you, the less 
profit generated for them by your business.

I cant count the number of "Tests perfectly!" that get resolved 
mysteriously inside the telco after some more harrasment. Furthermore, 
our experience on average is that the more the line costs per month, the 
better service you get on it. Typicaly with any large amount of 
circuits, you will find the right people in the telco who actually give 
a damn about you and can "get things done"
