Bad fiber and customer service

Bad experience with Vodacom fiber. I canceled the service in March because the fiber was very slow and most of the time down. They delayed the cancelation and only attended to my request in May. I was sent a credit note stating that I don't owe anything. The next thing I see a default loading at Trans union for R441 that I was never informed about. This has impacted my credit profile negatively and even after paying the amount supposedly owed still having the default issue. Poor fiber service and customer service
