Pathetic Service FNB Connect and FNB Care(less)

I needed to change my debit order date from 25th to 1st after my FNB Connect account returned unpaid because of changes in employment and pay dates. The consultant told me that I can only change dates after the debit order returns successful; and that I would need to phone back to change the dates. The next day the debit order is successful. I decided to call a day or two later to change dates but this time to the last day. The next consultant tells me that the date has already been changed to the 1st. She also tells me that if I change dates from 25th to last day there would be a break in service for those few days because the system is set to run for a month from 26th to 25th, and I my service would be disconnecting and that nothing can be done about that. I called my "team of bankers" but non was available. I emailed "care" but it seems no one really cares because I still have not received a response. I paid my phone debit orders on the 26th and they have run again on the 1st - I have been double debitted!
