Vodacom ***** and POPIA breach

I am extremely disappointed in Vodacom who allows subscribers to commit ***** on their customers sim cards. To my shock when I called Vodacom to the reasons why my app is not updating they rather informed me that I owe R451 700 as a outstanding balance. The said my number has been changed from prepaid to contract on 12/12/2018 by a company called RMCS (Blue Label Telecoms Limited) based in 75 Grayston Drive (Corner of Grayston Drive & Benmore Drive) Morningside Extension 05, Sandton, Johannesburg, South Africa. Vodacom provide no security to their customers and allow every **** Tom and Harry to steel their customers information and commit *****. You... "Vodacom" now pull up your shoulders and say there is nothing you can do - when you are the ones who told me that the sim is now contract. How did you allow or do checks that the sim legitimately went from prepaid to contract - in this case without the customers knowledge or consent. Vodacom is selling this information to blue label telecoms at a fee and allow them to convert customers to contract without us knowing. Vodacom must sort this sh#$t out with Edgars, RMC and Blue label telecoms.
