Horrible line and horrible experience with customer service

I have had many internet service providers however vox is by far the worst in terms of customer experience. I have called them regarding a problem for the past 5 months which they are unable to solve. I had the exact same Fibre package last year and it worked decently, however if you do have any technical problems they won't be able to help. After at least 10 separate calls talking to 10 separate people nothing has changed. I can't load web pages on multiple different computers and phones. This is a 100mb line which can't load a YouTube video at 240p. The technicians have hung up calls on me, they close tickets without speaking to you. I AM PAYING MONEY FOR YOU TO PROVIDE A SERVICE, IT IS YOUR RESPONSIBILITY TO PROVIDE THE SERVICE AND IF YOU CAN'T THEN WHY ARE YOU CHARGING MY ACCOUNT. Even after booking an appointment with the head engineer(or something) for 9 pm the day before they decided to call at 3 pm to assist and when I couldn't they confirmed to call at 9 however they called at 11 only. Even when somebody had been sent in the problem was apparently not on voxes side. So cool, I was told he would talk to frogfoot and call me back the next day. They didn't call. So after this horrible experience I am just left wondering what I'm paying for and what makes it worse is the wifi isn't just needed for games/YouTube. We use it for online studies at uni. I really recommend looking for any other provider.
