Vodacom - the most unreliable service provider

Vodacom must be the most unreliable company to do business with. I cancelled my fibre contract with Vodacom on 11 July 2025 and received the following e-mail - effective date for cancellation is: 01/09/2025 00:00:00. Up to date the line is still active with a result that my new Service provider cannot activate the line and it is now already 8 days later and I have to work of Mifi which is resulting in me incurring a lot of additional costs and Vodacom does not care.
