VODACOM FAILING TO RELEASE FIBRE LINE AFTER CANCELLATION WAS EFFECTED

It is near impossible to get rid of Vodacom Fibre. Month-to-month contract was cancelled during November 2020, with 1 months notice, service to terminate on 31 December 2020. Been battling since 1 January 2021 to get Vodacom to release the line and load the cancellation. When calling their call centre, I'm informed that the cancellation was approved (as confirmed by e-mails received in November 2020 already) - yet no-one seems to be able to tell my why the line has still still been not released, so that my new service provider can active their service!
