None compliance with POPIA

I recently made a cellphone contract with Vodacom and received a new number. On this number I am receiving an influx of calls and messages about Andrew. I have made numerous attempts to try get someone from the ISP to resolve this matter but even TOBi the sales agent bot is unable to assist because it cannot authenticate my ID. I am writing to Hello Peter to get their attention and resolve this matter urgently. I have been seeing information about Andrew that I am not supposed to see in respect to the POPI act law. This number is allocated to me but still belongs to someone else. I want a fresh clean number that has never been allocated to anyone else, or Vodacom need to ensure that the above is in order. If I do not get a call back as I have made numerous attempts already and also tried their 082 135 number which did not work for me, I am forwarding this to ICASA and FAIS Ombudsman.
