Clueless staff

I am having the worst experience. I get 2-3 calls from different consultants about my migration to Discovery bank. I have told all of them that my details on their system are incorrect and that I will not be able to migrate. I have sent the required documentation, but nothing is happening. None of the consultants seem to have a clue and they don't show interest, to the point where they hang up on me. Will I trust my money to this organisation? Not a chance.
