Struggling to get username and password

App**** for a new fibre line, installation has been done on ONT box through metro fibre, Telkom only delivers the routr and you have to set it up yourself, when phoning them for the username and password, technical tells you the line is suspended, you need to phone sales, then you phone sales and they tell you the line is active, you need to phone technical. Spend an entire day phoning between them and still have no username and password.
