Bad attitute and tone

On this day 07-05-2019 I received a call from a lady called Martha from Bankcol international who was extremely rude to me shouting in my ear about the reversal that I made on the 25 of April 2019. I tried to explain that I was not 100% sure whom the debit order was from hence I reversed it and she insisted I make a direct deposit immediately. I was very calm and asked if this is the way they speak to their customers and she tells me I should have just told her I am broke and hung up. I called her after a few minutes and she responded she was done with me hence she asked I should give a call back.

I have been handed over to this company because I missed a payment but I have never been shouted at and insulted by Nedbank collections before.

Still very disturbed by the way the lady spoke to me and would really like to find out if this is how they should handle their customers.
