very angry and dissapointed!!!

I'm very angry!!!!! I was handed over by bluebean or Standand bank in 2013 November because my account was in arrears to Nimble group. I then paid my balance outstanding in Feb of 2014. This whole time I thought my account was closed. Until I wanted to reinstate one of My credit card, they said I came up as a bad payer for R114.00. Today after almost 2 years I get a statement saying I owe them a 114.00. Where does this come from? I thought my accountbwas closed. Why do I still have this account and why was I listed as a bad payer when I wasn't aware that I owe them momey. I need answers and my name cleared!!!! I dont want this card!!!
