FNB credit card debit

Once again FNB is giving me the run around. About two months ago FNB decided to align my debit order date. this was changed to the 23rd of the month which i disputed. I was then contacted by a consultant which told me he will be able to change the date we decided on the end of every month. Last week i contacted fnb twice the first time was to confirm the new date i was told for the month of June the debit is still for the 23rd which i didnt have a problem and going forward the next payment will be 1 August 2019, however i received a message again stated that a payment is due on the 1 July 2019. This is Two payments in one month. I cannot transfer money from my credit card because of this outstanding amount that is nou due.
