MBD very unprofessional

My Woolworths account that I opened 2017 was handed over to MBD. I made arrangement with them to debit my account every 27th of each month so they started debiting from September 2022, to my surprise today they debited my account on the 15th. When I call to find out the agent says to me that it’s December people get paid early, the nerve?! I only get my December salary on the 20th. They basically stole my money from my account because no one called me to ask me when will I get paid in December. That money was for children to go on their trip with their cousins this morning, my kids had to stay behind. These are such things that cause depression for people this festive.
