Standard Bank activating accounts closed in 2013

I use to have a credit card and a current account with Standard Bank around 2010 to 2012. Those 2 accounts where settled in 2013 I was issued with paid up letters thst I still have on record. This year in October I started receiving statements on both accounts. When I log a complain with your Facebook team they referred me to your call centre. On Thursday someone called me and was then transfered to your legal call centre where a guy told me I am still owing.. Those accounts where settled in 2013 and updated on my credit bureau, how come are they suddenly active? This is *******. You can't not collect on an account after 7 years of no contact. Accounts that was settled. Since Thursday I asked for statements no one has sent that..
