Pathetic Service Stay Far Away from RCS!!!

I have been trying to get a settlement letter from RCS for a whole now, but nobody seems to be answering the phones. I cannot wait to close my account. Most pathetic credit provider in South Africa. Their service is extremely poor and I cannot understand how they are still able to be licensed according to the National Credit Act. I would please like someone to tell my why the emails take so long to respond to and why one cannot close your account with more ease like with other financial institutions.
