Rude manger, pathetic service

I am so disappointed in this company. I went under debt review in 2009. All my debt was paid in full in 2013. Since 2013 I am trying to clear my name. Guess what? No joy!! I spoke to the manager, Johan van Niekerk today, what a rude man. I am the client, but he was so rude with me, spoke to me like I am a nothing. I will not advise any one to deal with Randwise DMG at any stage. I want to buy a car, but now I cannot, because they are not clearing my name. I have handed in my documents in 2013 by hand. Emailed it to them a 1 000 times. I dealth with Dehan, Stephan van Straaten, Aneri Bonthuys, Hayley Cyster and Ilana (Clerk 18. 8 ,25) and how many more. Absolute pathetic service!!!!!!! How must I now go about to clear my name????
