Worst Service provider

After I signed my VOX contract, they became very difficult to work with Installation was meant to happen on the 29/7/2022 but only got done at their time, the router is in a completely different room to my TV so I was forced to purchase a signal box and still signal is bad, constant buffering and we are unable to watch a movie with out buffering and blurry picture every 20minutes, when I tried to get them to fix their mistake I was told I must pay more and when I tried cancelling my month to month contract I was told I must pay more. So I am stuck with VOX till I can afford to move, but they don't care they just want to make sure they get their money monthly, they don't care about you as a customer and will not help in anyway to improve their very poor service delivery.
