Zoom fibre - Homeconnect Internet - Unfair billing

This is the most pathetic service i ever came across, my internet has been off for the past 3 months going on 4 months.. Ive had no internet at all, no one called to check why and if everything was fine because obviously they can see that on their system that the internet had been off, i tried sending emails to support and the accounts email telling them i dont want their service anymore how can i be paying for something that is not working, but they still kept debiting me, i had to go to mybank and put a stop order on that, so that they would stop with the debits, now i can get a message saying i owe them so much, what nonsense is all of this, you people really need to sort yourls ****, i will not be paying for a service that was not damn provided to me!
