Linking a Koodo account

Hello!

Has anyone been able to successfully link a koodo account to their Telus account through the Telus website? Or even see the option to do so ANYWHERE?

Telus internet clearly advertised a discount for existing Telus OR Koodo mobile customers when I signed up a year or so ago. The option to link a Koodo account however has never existed anywhere. You can only link Telus accounts. 
Schockinly the discount was of course never provided. They keep promising they would fix it but I am still dealing with this and even a year later there is still no way for a customer to link a koodo account.
It feels very much like a scam and like they should not have advertised a discount that is impossible to get????
