Pathetic service

I am extremely upset with the pathetic service received from Nedbank customer care. After calling in about 6 times requesting a debit order date change on my personal loan. After numerous calls the debit order date was changed however this resulted in my account being debited twice. the 24 May 2019 and again on the 3 June 2019. The requested date change was for the 2 June 2019. After multiple calls once again requesting that the debit order be reversed i was told a different story by all your consultants. I am extremely frustrated and this resulted in my facing unnecessary financial difficulties.
