HARASSMENT AND BAD SERVICE

I have African personal loan that went into arrears when I went under Admin in 2012. African bank has never stopped the or even reduced the interest on the account until 2016.When I had lost my job the admin order had been cancelled, so when i started a nee job i called in and made payment arrangements to pay each month to which i have stuck to the arrangements without fail.I have stopped paying my African bank account in January I had sent an email as well as on numerous occasions asked that the interest be reversed which was never done WHEN I ASKED FOR A COPY OF MY CONTRACT THE AGENT HAD A NERVE TO ASK ME WHY I WANTED MY CONTRACT.FROM THE BEGINNING OF FEBRUARY I HAVE BEEN REQUESTING A COPY OF MY CONTRACT TO DATE IT HAS NOT BEEN RECEIVED.I HAVE ASKED THAT THE INTEREST BE REVERSED NO ONE HELPS. I TELL THAT I A UNEMPLOYED THEY HAND MY ACCOUNT OVER.THEY ARE QUICK TO HAND ACCOUNTS OVER AND TO CALL YOU EVERY DAY BUT NO ONE ACTUALLY CARES IF YOU CAN OR CANNOT MAKE THE PAYMENTS,BUT WHEN I MADE THE ARRANGEMENT IN 2015 I STUCK TO THE ARRANGEMENT SOMETIMES EVEN PAYING BEFORE THE ARRANGEMENT DATE.THEY DONT HAVE PROPER CUSTOMER SERVICE NOR DO THEY MAKE PROPER NOTES ON THE SYSTEM IN ONE DAY YOU GET 5 AGENTS CALLING YOU AND YOU HAVE TO REPEAT THE SAME STORY.THEY DONT CARE ABOUT PEOPLE EXCEPT THEIR MONEY.ITS ALL JUST ABOUT MONEY TO THEM THEY HAVE NO EMPATHY FOR ANYONE.IF SOMEONE CANT PAY R26000 HOW CAN YOU EXPECT THEM TO PAY R43000
