Vodacom facilitates theft

I took out an LTE contract with vodacom for R599 per month and at the start of 2022 I received a bill exceeding this monthly fee. I queried it and turns out it was these entrainment services that charge you daily or VAS services with a daily charge. I was told how to block these on the app and vodacom credited me the excess amount I paid. A few months ago I received another account from vodacom and there was an entrainment fee again added to my account which pushed my account over R1000. I checked and the blocks were still in place. I emailed vodacom to resolve the issue but was told that they would just stop the service but no credit was given. The next month I received another account for over R1000 and again I contacted vodacom and lodged two disputes regarding these accounts. I have not heard from vodacom or received credit. These services were not approved by me. I did not sign up for them and in fact they should be blocked so they could not rack up these huge bills and yet I had to pay. I'm disappointed and seriously irritated with vodacom's service.
