Why not Cancel?

May 8th, 2021, l sent my cancellation order of fibre line to my home to Vox, unfortunately was sent to no reply server of which l sent proof to Vox days later! Also May 8th, Tania Pretorius whom cc’d in Amy John, l sent her correspondence of my cancellation! May 24, l sent proof of my cancellation emails, several ref. no (VOX***5/ VOX***7/VOX***0-T1 and still Vox not cancelling my order! I have received no router, they have not received any bank details from me so why keep me hostage as l don’t want to be a client! I can’t move forward with my chosen network because of VOX! My telephonic discussion earlier l was told it’s at retention! More than a month ago l cancelled! Disgusting behaviour!
