********** debit order after contract cancelled

Account 0000 106 00 was confirmed as being cancelled by Lebo Phaho in an email on 4 March 2015. Since then the debit order has not yet been cancelled. My mother, the client and a pensioner, has had to go to the bank every month to have the debit order reversed. This month the amount was also amended from R159.99 to R319.98. This is yet again unacceptable.
