Cybersmart Limited review: Billing account

Good day,

I have experienced many downtime with this internet provider due to maintaince they were always doing and downtime I still had to pay in full for the service, this year january 2023, I had asked them to cancel my contract due to the fact that I had to move from the complex due to end of lease and informed them that I will not be using their service they refuse to cancel my contract and informed me to make an agreement with the new tenant to pay for the service which I did not use in febuary 2023 because I was not occupying the flat. I have now received a legal fee that they want me to pay. I do not understand why I require to pay for a service I did not use and I still paid for downtime in full these people constantly harrass me and wont leave me alone please help.

The internet service was provided by ftta which falls under cybersmart.
