Get billed for no service

We received Fibre in our area, Telkom people was coming around and looking for customers. I have LTE from Telkom and asked them if they will cancel my subscription if i decide to take their Fibre option. The lady said i must complete the form and she will find out and come back to me. She never came back to me so i went to Festival Mall Telkom office and asked there and they said no i had to finish pay my contract they cannot carry the LTE contract over to the Fibre contract. I then received a Telkom rooter and called 10210 and asked them to come and collect the rooter as i am not taking there service. The consultant promised that she will cancel this rooter and arrange for collection. This morning i received a bill of R1496.85 for a rooter that is still sealed in the box and waiting for telkom to collect. I went back to Festival Mall with the sealed rooter and the bill as nobody came to collect. They adviced me again that i must call 10210 and canceled the rooter. I called again and the lady Mabiela Pietersen told me that i must open the box as she needs some information in the box. She was looking for a sim card and there was no sim card in the box. She told me that she had cancelled the contract and arranged for the rooter to be collected but i have to pay for one month???????????????????? for what????????????i have not used this and when i signed the application form it was on condition that my previous contract for LTE was cancelled.I went ahead and got fibre from another company in January 2019 I WILL FIGHT THEM IN COURT I WILL NOT PAY FOR SERVICES THAT I DID NOT USED.
