Dial up troubles up date

Hi all

Just a quick up date on my problem, I thought I would try using an old supanet dial up connection one I us to use before they change the dial up number, guess what it worked, dial up window came up, clicked onto connect, dialed ok and this did not ask my to confirm password as before the box is ticked for save password anyway, connection made home page loaded (supanet) however the homepage then changed to "change to supanet dial up" this I have seen before, it is a series of pages that takes you through re installing a supanet update now to include a new dial up telephone number.
Anyway as I did not continue any further at this point I believe that there is no problem with my computer it self, just the confirmation of user details durning dial up when using this latest telephone number change, mind you by latest I mean the last 6 months, for the record this is the 3rd time supanet have changed my dial up connection telephone number in 2 years.
Dare I continue with the number change procedure when using an old telephone number or just install a new supanet isp cd rom?
Has anyone got Supanet.com customer service telephone number.
