Vodacom renew contract without my permission: Part 2

Last week, I wrote a review stating that the contract was renewed without my permission. I was contacted by Vodacom, and an investigation was done. On Friday, I was contacted and informed that I did not renew the contract. I was informed that I would be refunded an amount of R423.00. I paid this contract for a year while trying to get them to investigate, which they did not. I was taken to debt collectors, and my credit score was affected. What must I do with Vodacom contacting me and saying sorry? Please tell me what I must do with your apology. After all, I am the one who lost money, not Vodacom. This is how we consumers are being treated. Just imagine taking me to debt collectors for something I did not even agree to. Then, sorry just like that.
