Axxess unjustifiably demanding early termination penalty fee

I started using the fibre service of Axxess on 2022-02-02 and prior to signing up informed Axxess that I will have to submit a move order for around 2022-02-18. This was due to us moving to a new residence and I urgently needed access for the period 2022-02-01 to 2022-02-18 for work purposes. Now I am being told that I will have to pay an early termination fee of R999 for my current line (activated on the 2022-02-02) because I am moving to a new line at my new residence on 2022-02-18. I have already signed up to stay with Axxess for the new residence and even upgraded my line speed! I am giving Axxess the opportunity to rectify this issue and I will up this rating when this unnecessary complication is adequately resolved. Thank you in advance.
