Still being debited

I was in arrears with capfin and after receiving my statement for April it stated on the statement that I have that my balance was +- R1300,00 (R662,50 as well as R600 arrears) and for the month of May 2015 as well as June 2015 my banking account was debited for the amounts of R662,50. I left it at that, then I got debited again on my salary for July 2015. how does that work? I want my moneys and bank chargers refunded and back in my account, this is theft. I want it to be reversed and my loan account closed and I will not have any further dealings with *******.
