DISGUSTING service

My car installment goes off my account on the 22nd of every month. In the month of March- the installment went off on the 20th (due to the public holidays). I only get my salary on the 21st hence my reasoning for setting my debit order date for the 22nd. FNB charged me R150 for not having a bounced debit order. When I spoke to FNB they said to speak to Wesbank as they took the money from my account at the incorrect date. I spoke to a Wesbank consultant today and she said there was nothing she could do. I fully understand this is not her fault but I am extremely annoyed as I set my debit order date on the 22nd of every month for a reason and then I get money taken out of my account TWO days before!! And I get told that Wesbank can't reimburse me the R150 or help me. Things are tough for most people these days and to be charged an amount of R150 for something that you didn't do/plan for is absolutely ridiculous. It is blood money! I asked to speak to the manager and the consultant said they would call me back and I yet to receive their call!
