Mbd is the worst company I've ever dealt with!!!

I paid all my accounts in January 2019 and till this Johanna who is supposed to send instructions to all bureaus to have my information updated hasn't. I contacted one bureau, she was sent an email and still has not got back to them after a full week. I call in and my calls everytime they transfer gets dropped. Today I asked for her manager and I was given a number that does not go through. What should one do in South Africa before they receive a good service!!?? Why should we always fight before we get a service we deserve. I want to hear nothing from Johanna, can someone assist me ASAP before I take this matter further.
