Card account blocked without informing that they required FICA documents.

Last month I cancelled my credit card which I had for about 40 years. It took about two weeks to get them to attend to the closure of this account. In 2014 the card was blocked when we were on holiday as they required FICA documents. This without requesting the same. They they also did so in 2018 & in early July 2022. I emailed their FICA department inquiring why they blocked the card without requesting for the documents they failed to respond. I was charged bank fees for July 2022 on a card that I did not use in July as it was blocked & interest on a account was always paid before due date. I paid the account in full as I did not want to delay the closure of the account any further. It is unacceptable for Financial Service Providers to treat their customers unfairly.
