Unauthorised Personal Contact details being changed

My Multichoice saga continues. After 3 visits to the 'Customer Care' centre in Randburg and numerous long phone calls to the Call Centre a very capable call centre operator by the name of Yerusha resolved my account issues. She aslo verified my contact details - email and phone numbers. Today, when trying to log into DSTV from my browser the system sent my login authentication message to a foreign phone number which i have never owned. So, between Saturday afternoon and Tuesday morning someone who has access to the Multichoice customer records has gone in and once again changed my records. This is definitely now a case for my attorney to open a claim of infringing the POPI Act against Multichoice. Lets see what happens now.
