Worst service delivery.

I haven't had internet access for a month already and it's been 2 weeks long now since I logged a query regarding the matter at hand, I'm expected to pay my monthly fee/charges come monday and yet I don't have any access to internet, I'm working from home and had to get an alternative router wich is costing me precisely the same amount I'm paying for on my new 5G CPE Router and simcard. I've fallen behind on my work and studies, had I known this was gonna occur, I would have never took the contract. I'm so disappointed, frustrated and hurt. I've been calling the company almost everyday for the past 2 weeks, they keep telling me the matter is being escalated, yet it can't be resolved. If there's anyway I can cancel this contract and save my capital, I would gladly like to do so.
