Worst after sales support from Vodacom

Worst ever service I have received. I put in my cancellation request on 2020/08/31, 30 days before my requested cancellation date (As per the Vodacom Contract). The request was for the 1st time only action on the 2020/09/06 as per the automated response I received. It was then only again touched on 2020/09/15. Then only on 2020/09/21, 5 days before my my requested cancellation date was the cancellation quote sent to me. Which I completed and sent back. Since the 25th Every single time I call the only feedback I receive from the Call Center is that I must sent through the signed quote. Which I have done. No-one can give me feedback on the actual cancellation date (it is now nearly 2 weeks after the requested date). No one can put me through to anyone who can resolve this issue and their so called "escalations" to the powers that be have to date not yielded any results. Vodacom has never since I started using their service failed to debit my account for the money that must be paid. But now that I want to have the service canceled they are dragging their feet. On top of this since putting in the request my network connection quality has been "mysteriously" up and down for the better part of a month. Coincidence? I think not.
