I have a Telecom account with an old xtra email address still attached to it. Until last Friday I also had a XT number attached to it just for mobile data. Since I have not used it for a while I decided to cancel the XT number.

I am now trying to get to Your Telecom to check a pdf with the last invoice to find what's the account number, and it says "Sorry, but this service is temporarily unavailable".

I know the service is no unavailable, since it works well if I use my personal account details.

How can I get access to Your Telecom now? Of course I might call 123 and go through passing company name, etc to try but I doubt they will let me go through if I don't have an account number...
