Thieving, FNB lying and steeling every chance they get

I transferred funds between my savings account and cheque account yesterday (30 July 2020) to cover my debit order. This morning I wake up to a notification that the debit order was unsuccessful (No details in the message so I had to go through the PT of investigating). When I checked my transaction history it shows that the debit order went off on the 30 June 2020 while the transfer went through on the 1st July 2020.

Please FNB! I have a screenshot of the date and time the transfer happened (between my own 2 accounts before the debit order ran) Do not try and lie to me so you can make an extra R110.00 for a declined debit. You will need to rectify this asap otherwise I simply move my accounts. I will not be another victim of you *******.

You need to sit down and think hard about how you rip the millions of people off with your exorbitant fees (R110.00 is most of this country's weekly groceries!)
