What do I do?

[86JR]

For some reason as of 3am yesturday to 1pm today my internet has been out. I think it happened at Zen end because I had to re-enter my user/pass to connect.

But now I can only get 5mbps instead of the usual 55mbps.

Have I been downgraded by the DSLAM? How do I get it back up?

Thanks
