Fibre cancellation

I have been with Vodacom as my ISP for fibre for a while, but my internet kept dropping, and I decided to change ISP. I notified Vodacom to cancel my fibre in April 2024, and they said it would be terminated end of May 2024. Internet was cancelled beginning of June, but I cannot get connected with new ISP until the fibre line was freed up, and that will only happen on 16 June 2024. So I cannot get fibre until then. Called them 3 times already to ask if they can move the date forward. Every time they log a ticket, but nothing happens. Very frustrating.
