Unprofessional

I'm one of the customers who had a credit card with Nedbank and due to unforeseen circumstances, i was unable to meet my payment commitments. I was then handed over to Brooks and Luyt. Why would a company like Nedbank choose to be associated with a business like Brooks and Luyt, can someone please explain this to me. I have been requesting a statement for almost 4 weeks and i have received nothing from Brooks and Luyt
