NBA Banking details hassle

My account was handed over to NBA, and they phoned me on the 22 Oct informing me about this. I requested that I get the statement reflecting the amount I owe. I received an email on the 23rd, without the statement. I then sent an email in which I made a monthly payment undertaking to pay off my debt- This was responded to by Rafqa, still no banking details and statement- but advise to get a discount or pay at Checkers etc. Today I sent another email requesting banking details again, this time it was responded to by Louise van Wyk- advise and Checkers whatever- I rep**** requesting the banking details only to get the same message and a telephone call, I had to repeat my request only to be told NO unless I told the lady how much I wanted to pay- I refused to say because I had already written the amount in an email which they have in their possession. When I asked for Rafqa, I was told she was not at work and that she will only be coming back on Monday. I then requested the details again without success. What kind of business would not give you their banking details on request,esp if you want make a payment? No wonder so many complaints about them I wonder why WOOLWORTHS is using NBA?
