BAD ATTITUDE - DEBIT ORDER STOPPED

I have had Issues with MBD regarding my Woolworths Account since 2014 and in 2015 I made arrangements for my account to be debited up until the amount owing is paid off , MBD debited my account in MAY and after that stopped and when I followed up on the 03/08/2015 to finf our why my account was not being debited I was told that WOOLWORTHS closed the file , I spoke to GONTSE @ 15:05 03/08/2015 , I was told to call Woolworths and spoke to Luleka and she said it was handed to Brook and Lyt and I was now owing R658.92 , I then spoke to Monica Woolworths and she said I should send her a mail and she will get the person dealing with the account to call me but instead MBD (FLORA) called me this morning and was very rude and said that they did not stop the debit order , I then said if the debit order had not been stopped I would have been free paying the account by End of JULY , I then requested for MANAGER from MBD to call and have not received the call as yet, WHY was the debit order stopped NO reason can be given from MBD SIDE WHY???
