Early debit order and account behind

Dear Standard bank, how much emotional and financial pain you have to cause to someone life in order you as banker realise that you causing harm in someone life. December is my birthday month. I have saved money to celebrate my birthday and also take care of my family in December. I’ve released the funds to my bank current account around 17 or so , realised this funds in preparing of going home, eastern cape . The bank decided to do debit order and take the bulk of the money that was on my account. I then call the bank call center. The consultant was speaking with gave me two options for reversal. 1 option was that if they reversed the money I will have to do manual payment the 2nd option was that someone from the bank to do manual payment on my behalf. I declined both options. What I was requesting was that they reverse the debit order and run the debit on the agreed debit date which is the 26th. The consultant said it’s not possible for a debit order to be ran two times a month . We ended the call with me rejecting both options. Then someone from the bank did reversal without me authorising it and they did not call me to tell me on what basis they do reversal. I saw it from my bank statement that they did reversal then I call the bank to ask who did reversal without my authority the bank did not gave me any tangible explanation besides the consultant I was talking to just said to me if I want I can bring my lawyers. Being told by someone from complain to bring lawyers if I want to was hear breaking. I had booked accommodation for my birthday which I already paid deposit now I had forfeit the deposit because I did not have any funds on my account. I could not even get to my family as planned which was the most depressing part . Could not do the December preparation that I normally do for my family because I did not have money because the bank the Monday after they did reversal they went on did another debit. At this stage was confused. Why one will reverse the money then debit again the next day . My account was suddenly on then go negative. They even went as far my overdraft. I had hours of calls with them using my airtime. Then the complain department got to a resolution which I felt is not even a resolution to me. They said they give me R500 on my credit card . Which was a drop in an ocean on what they cause me emotional and physical. The last call I had with them was to tell them they must do whatever they need to do but need to make sure any of my accounts are not behind. Now there is someone from Standard bank calling me saying one of my account is behind and it’s listed on ITC. I ask them how did this happen, because when the debit order rerun I had money how did they not do the debit. The lady said it was the banks fault. Saying it’s a banks fault but the implications are high on me as my credit rating is negatively impacted. I don’t know what to to with the bank anymore besides taking my accounts somewhere else.
