Slow account update

I made a payment on my platinum credit card which was over the limit. The payment more then covered the over limit amount and then some but I can't access my funds. I am only able to access my funds on the following day cause your **** system can't update automatically and you rely too much on human intervention. I also have a platinum credit card with FNB and as soon as a deposit is reflected in my account that was over the limit, the amount below the limit is available immediately. You really are a **** poor bank. I think I should just close all my accounts with you cause if it's not **** like this it's stuff like whenever you require something or I do I need to go into a ****** branch to take care of the issue. I have not set foot once in an Fnb branch in over 2 years yet with Absa I can recall at least 10 times where I've had to go into a branch to resolve any issue. Get your **** together and who knows you then might just turn out to be a bank of choice!
