Personal Information not Save - Harassment

Dear Vodacom Sales Department. I have been logging the same call over the past 2 months now and feedback is just empty promises. I have been harassed by one of your 3rd party contractors who has access to all my personal data which to me is very high risk. Vodacom however chooses not to resolve this matter and I have been following up endlessly with no feedback. On the 24th of August I spoke to a consultant who sounded serious about resolving the matter and providing me feedback. Unfortunately this person also disappointed. Both Luyanda and Akshay committed to give me feedback in 13 hours more or less(Strange time). I was advised the matter has been re-escalated (Ref230823). Since I have not heard anything back from the team who committed to do so, I called in again on the 11th of September. The agent at the time said to me she could not pick up anything on my profile. No surprise. I then quoted the ref number and asked to be put through to Luyanda. She then asked me which Luyanda, as there are 3. Strange again, as whenever you ask an agent for their surname the first response is they are not allowed to give it out. The agent advised me she could pick up on the system who the person is and are going to put me through to her. She also committed to following up with me the next day (12 September) . This never happened, again no surprise. She then proceeded to put me through to a queuing system, and not Luyanda as advised (No surprise there. This is a risk and my personal information is with a 3rd party appointed by Vodacom and Vodacom does not give a single damn. So much opportunity to reolve.
