Shocking customer service from Vodacom Fibre - Cannot cancel Fibre line

Terrible service from Vodacom Fibre department. I requested my Fibre lines cancelled on 10 March 2021. I received and email stating that the effective date of cancellation would be 01/04/2021. I further received and email on 12 March 2021 stating that " Your cancellation request has been submitted and approved.". To date I am still being billed each month. I have called multiple times and always receive some excuse about documents that should have been emailed to me to sign, but I have not received any other communication from Vodacom. Absolutely shocking customer service.
