Most disgusting bank service I've ever experienced.

I moved accounts to absa bank a few months ago. Worst banking decision I've ever made. I got ripped in bond arrears for no reason which I eventually paid cause I couldn't take the stress anymore. This is the 3rd week trying to close off my credit card with them. Last week I even had to block it so that no one tries anything funny with that account. I've been calling these fools and each time they tell me that they 'can't reach' the cancelation department but they will send them the request to call me back. How difficult is it to close an account? Definitely moving accounts from this *** service.
