What is the purpose of having a ***** division that doesn’t want to assist?

Worst experience ever. Firstly no option to report the ********** transactions on the app or email notification. I had to call your call centre. I informed the gentleman that there was a payment reserved on a card that no longer exists. He then started interrogating me as to how I knew that the card no longer exists. He proceeded to confirm that the card was destroyed, yet a transaction was still allowed through? How is that possible? He kept on repeating “oh so you are saying you want me to open up a ***** case?” And that there were previous payments done with that card, why wasn’t it reported? Why would I report a payment on a card I had at the time? The card in question was destroyed 2-3weeks ago, and a transaction went off today! That’s why I called your ***** division! Which is of no use whatsoever! Just another call center agent clock watching!
