Bad customer service and Manipulative service provider

I contacted customer on the 22/10/2022 because my internet was down , the issue was not resolve ,upon speaking to 8 consultants and after the probing process was conducted no solution was achieved . I continue to contacted them daily until I requested Cancellation department Zoyisa who refuse to provide her full name to cancel the service on the 31October 2022 , she was just arrogant all through out the process and I was advised of the calendar month notice and that it start from a complete new month start to end , which was suppose to take effect from the 01 /11/2022 until 30/10/2022 . I received a billing request and that my account has been suspended for not paying how was I suppose to pay for the services that was not rendered from the 22/10 until I do not know when because my internet was down and now I am held at ransom because they do not want to release the fiber connection for another service provider. I received the cancellation confirmation on the 01 December 2022 however they blocked the service which is the Vumatel line connection I paid for ,
