ABSA *****ing my money

I am absolutely shocked... I'm wondering if ABSA often stabs long term customers in the back and ***** their money? After being a customer for over 10 years, having paid over R12 000 in bank charges during that time, ABSA has made it almost impossibly difficult for me to close my bank account. Furthermore, you continue to deduct bank charges from my account, which I have been trying to close for 7 months now, and claim that it cannot be closed until I pay those charges. Numerous phone calls to customer support, reference numbers to prove and visits to the bank. I was happy to pay the closing fees but not to pay the continued bank charges after the fact. That a bank continues to take one's money while they refuse to close the account when one is no longer a customer. Quite frankly, this seems like theft! Now I got a nasty legal sms.

I also messaged on the social media page and followed their suggestion, the person who responded with a "resolution" had not understood the matter at all and simply summarised the events.

Is this how ABSA treats all their long term customers eventually? What have others experienced?
