Bad service

So FNB offered me a cheque account which I accepted. I then did the debit order switching and mailed it about 2 weeks ago. Now I realize that it hasn't been processed. When I called to find out why, I was told that it takes 4-6 weeks, something I was never told when I sent the form. Now I'm expected to take care of the matter myself, that's what I was told. What a lot of ********. I just joined the bank and already I'm experiencing bad service. Good bye FNB, I'm taking my money elsewhere.
