Worst experience in my life

Dear RSAWEB, if I could give you no stars, I would. I have placed my order on the 30th of November 2021. My estimated live date was the 29th of December, when I phoned to make a follow up (since the 30th of Novemver I have not received any update), I was asked to send pictures of my current installation at my address, which I did, I made sure I sent photos of every last detail...a few days later I was contacted by the courier for my delivery of the router. I received the router, but no installation team came out to set up my fibre. I phoned and was told that I need a fibre box. After almost 15 phone calls and 20 emails back and forth, I decided to cancel my order - my order has been cancelled the 26th of January.. I am still receiving bills for fibre and I was never even live - its been 3 months now and for some reason I have magical fibre.. My fiance actually phoned MWEB after I cancelled my order and I have been with MWEB since the 5th of February... I am still being billed for Fibre ?? I have queried this and all I get is " we will look into it" - how difficult is it to see that my order is canceled and I was never live???
