Vodacom Fiber do not care about their customers.

I am now very frustrated. After a migration was done on my Vodacom Fiber service on the 05th August 2020 I am battling with network connection and download speed. I phoned a lot of times *** and spoke to various consultants about my problem. since the 6th August. I have so many reference numbers and even more promises. I even Emailed them and used My Vodacom app and went on their Facebook account for support. All I am getting is please be patient I am still without network connection. What more can I do but cancel my contract with them.
