Increase of premiums

As a customer of ADT, in June 2023 my premiums where R286-20, In July it was 343-70, when I called to query why the increase I was told it is for self city cameras, I complained and received a call from Ms Zoleka and explained to her why should I pay for cameras which isn't in my street and they just increase my premiums without notification. She promised to remove the premiums for the cameras and refund me the difference and i mentioned to her to look into my premiums and call me back with an offer but till date she has not called me back nor refunded me. On 18 July I received an email stating that from 1st August 2023 my new premiums will be R371-20 due to an annual increase. But they took R406-19 and when I called to query, I spoke to Surprise Mashimbye who mentioned to me a service of secure fire was added. I said to her how can they add services without consulting with the customer first, she responded and said communications where sent out to customers but she could not prove to me that they communicated with me. I told her about Zoleka and she mentioned that she is going to escalate the matter. In the last 3 months my premiums where all different amounts.
