Clientele’s debit order mistake corrected 7months later without any apology or notification

My Banking app advised that clientele debited my account for the second time this month.I spoke to a lady advising me that the relevant department is currently closed and will be available on Monday. She was kind enough to take my ID number and pointed out that I had a missed debit order in the month of March 2021. My banking app confirmed that the March debit order went off on the 19th as opposed to the agreed upon date of the 22nd. My question is WHO GAVE clientele PERMISSION to debit my account on the 19th (March)?Clientele still has the audacity to perform debit order CORRECTIONS(7months) without my consent or a simple email or sms to advise? Why should I have to be inconvenienced for clientele’s incompetence? The biggest sign of disrespect and no regard for your “stakeholders “. Let me prepare myself for a useless apology…Highly disappointed
