R2000 penalty fee to cancel a month-to-month Vodacom Fiber line.

I have a Vodacom Fiber line - I have a month-to-month contract. I'm moving and phoned them today to please move the line to the place I'm moving to. Unfortunately, there isn't fiber at the new address....so I told the lady who assisted me that I have to give a month notice to cancel the line. Then she told me that I will have a penalty fee of R2000 because I cancel the contract. But my fiber is a month to month..... I need this sorted please - I'm moving by month end.
