No service

I have this problem that I have never received a monthly automated invoice for my Fibre for more than a year. I have called in about this numerous times and each time it was escalated to the billing department. I've also been logging tickets via the app about this for months. Still I don’t receive anything. And I can’t even retrieve it myself via the app or the website because both give me an error. My email is *** and I’ve been receiving my cell phone invoice on it for years. I’m sick and tired of having to call in each month, spend 20min on the phone just to get an invoice.
