DISGUSTED AND UNPROFESSIONAL FOR SUCH A GOOD BANK

On the 2nd of June we made a manual payment of R4474.98 into our standard bank account as there was an issue with my account, therefore as a responsible client I made arrangements that I pay the account on time to avoid the debit order being unsuccessful. Then on the 6th of June my account was debited, which was returned and I was charged R110.00 for the returned debit order yet the instalment was paid on the 2nd. Today the 23rd of June my account was debited again for an amount of R4461.28, for what? I would like to know as the agreement I signed was the debit order to go off on the 6th and the home loan account is not in arrears. Last month we spoke to Shan Billings & he assured us that he will sort this out for us but unfortunately he didnt as there was an attempt on the 6th of June then today more money was debited. I would like the funds be reversed today as this is the money for my debit orders that will go off on the 25th.
