Disappointed

I have a home loan with absa,my debit order normally goes of on the 28th I phoned in a week before my debit order went off and asked if I can move it to the 27th the guy I spoke to said there will be some changes to my account,so I decided to do a transfer straight to my bond account and i called in I was told that it is showing but will be cleared after 24hrs. The following week which is last week. I phoned and I was assisted successfully,the lady that assisted me knew her job perfectly and she also confirmed that my account was paid. Now my worry is today on the 8th of July I received a debit order and an unpaid debit order for my home loan my concern is why does absa keep debiting money while my payment has been done and it even shows on my app.and at that moment I will be charged an extra 150 for the unpaid debit order that absa is purposely creating.I am not happy coz this month you took 150 from my charges for an unpaid bond that has already been paid and next month you will do the same coz you keep debiting the money that I have already paid and my account is on 0.00 but still you are debiting.I am just waiting to see if I am going to be ****** this 150 for this non existing unpaid debit order.this really breaks my heart it actually hurts because I cannot be paying for debit orders that absa decides to do.i am so disappointed with absa really.this is day light *******.im hurt
