ISSUE NOT RESOLVED AFTER FIRST COMPLAINT!!!!

I had laid a complaint regarding my account which was handed over to \VVM "who still won't give me my settlement letter after I had settled my account. I got a response from capfin telling me the matter was resolved. How is the matter resolved when I still haven't got my settlement letter? I called your accounts department and funny enough my account is still showing that I'm owing. VVM had initially promised to get me my settlement letter 7 days after I make the full payment to this this day I haven't got it. They are now telling me about 31 days. HOW IS THAT POSSIBLE? THIS IS SURELY THE LAST TIME I DO BUSINESS WITHOUT CAPFIN AND TO EVERYBODY THAT'S ABOUT TO I'LL ADVICE THEM NOT TO. NOT EVEN YOUR LG AL OR COMPLAINT DEPARTMENT HAS BEEN OF HELP."""
