The nonsense of Outstanding Card Authorization

I cannot believe this!! Standard Bank and your delayed Card Authorization Swipes, have completely thrown me off my budgeting. They keep saying it is cheaper to swipe your card than to keep withdrawing cash, what they don't tell you is that when you swipe is that you then have an Outstanding Card Authorization. Which is meant to reserve the funds that you have swiped for of which will be taken by the merchant a couple of days later. Banks should not allow this!!!! I have had to take out a loan, and guess what? Today I woke up to find those funds also swallowed from the stock piled card authorizations all coming in at once, mind you i also have a statement i took on friday and when i look at this morning's statement it is completely different. I am royally ****ed off man. The bank didnt even explain that these are the flaws in having a cheque card that i pay a lot of money to have, every month with the bank charges.. You people have my details, please hurry up and sort this nonsense out.
