********l charges on my closed contract account ***

I cancelled my Telkom contract 3 years ago,because they declined my upgrade then,so after 3 years they decided to debit an account that is not in use anymore for the amount of R37.49 ,an amount that I don't know where it comes from after 3 years,so they charged r240.19 because the debit order came back unpaid and another r202.70 for the 2nd month's debit order unpaid--this totals to a crazy r442.89 which I will not pay because where does the r37 come from after 3 years,Telkom is a ******* and I want the rest of the world to know how sneaky they operate.Reverse all these charges and close off the account -*** MISS LCP VD MERWE Conctact nr ***
