Being harrasshed!Vodacom is responsible!!!

I have been a loyal vodacom customer for many years, despite having numerous issues with the provider. The latest is being stalked by a person who claims he got my personal information from vodacom's database. The number that he calls from is ***. This person has been calling me quite a few times. I don't even answer the phone. Now I get short frequent missed calls from this number. <br> Yes I can block the number. But what is the use if this person will just keep phoning again from a different number?!! Now this is why we have a contract Vodacom!!!! My personal details are to be kept quiet, and PERSONAL!!! If I do not give you consent to SHARE my personal info, WHY WOULD YOU DO SO?? My personal info, like email and ID number and address has now been made known to a *****!!!<br> <br> I DO expect an explanation from Vodacom!!!!!! How will you make this right???? And how will you prevent this from happening again???? I am now afraid to even answer numbers that I don't know!!! I am also losing business this way because I'm too scared to answer any calls!!!!<br> <br> You better fix this...I don't mind warning others on social media OR moving to CellC!<br>
