Unsatisfactory service.

2020 I used my 060 number for whatsapp but it required me to verify. I couldn't as I want able to find my Sim. I never knew that the number was already given to someone. When I found out I phoned customer service and I had to go to Vodacom outlet. They confirmed that I haven't used it in 3months and was given to someone else. The strangest part was that my 060 number was trying to get in touch with my contacts. Two of my contacts confirmed it and when I reported to the police they advised they cannot do anything as there was no harassment. I wasn't able to open a case. At the outlet they contact the number and found out its an African lady but the profile Pic was a Indian coloured lady. This was suspicious but nothing Vodacom can do. It was not my number anymore. I also visited the same outlet in relation to my 082 contract number that was changed to prepaid some time ago. I was using it but somehow on my Vodacom app it was connected to a email address that was unfami****. Through the technical staff and call centre no one could reset or resolve the matter. So my OTP was send to the email which had a backup email connected to my wife. I confronted my wife and she did not want to cooperate. Vodacom did not want to assist further. Both numbers I've used most of my time with Vodacom and certainly the service should have been satisfactory. It wasnt. I had to go there time and time again. I'm unhappy and had to change my numbers. I was advised that I can't block the number unless let it run out for 3 months according to protocol. Never had I experienced this. Please advise to your course as I'm done trying.
