Vodacom failed to do their job

Cancelled my fibre with Vodacom in Feb after my internet was down for more than a week. Was told I have to give one calendar month's notice and line will only be released on 1 April 2025 00:00.I received email confirmation that my fibre will be cancelled at the time. Of course it's now 3pm and the line is still not released because they never sent Vumatel a ticket to release the line. Only after phoning them multiple times today are they saying that the ticket has now been sent to Vumatel and now I have to wait another 72 hours for them to release my line so I can sign with with another ISP. What have they done for the last month and a half that I have had to wait and pay for?
