Debit that did not go off

Good Morning

I am highly disappointed to the i-direct collection department’s agent Lucky Khoza , I called in concerned why my debit order did not go off on the date as agreed and the reason of my call because last month I also had the same issue and which is worries me because it will affect me in the future should i want to do a claim. The way he was screaming at me on the phone was unacceptable because as a customer I am making sure I’m doing arrangements for the money to be debited again but the way he spoke to me it’s so disappointing I ended up keeping quite after advising him I was not fighting with him I was only raising concerns I expect better from Absa not people who don’t understand customer service but who thinks they know better than the customer.
