Honoring Fee ****

For the second time this year Standard Bank has charged me an honoring fee for grocery store purchases. The 1st was for around R60 for a purchase of that amount I made at a grocery store and the second for an amount of R100 for a purchase of R295 I made at a grocery store. Now when I look up why Standard Bank charges honoring fees, I see that they charge these fees when a transaction goes through an account that does not have enough funds to cover it. What confuses me is that on both trips to the grocery store, I made purchases using my account when the funds were available. I'm not stupid, I wouldn't go and try to make a purchase using an account that I know has no money. Both times there were sufficient funds available on the account and after the purchase was made the funds were no longer available for me to use as per normal. When you use R10 on your account, your available balance becomes R10 less than what it was. This happens in my other account with a different. However, with Standard Bank, I'm being penalized unnecessarily so. So now I have to pay for my initial purchase and again for honoring fees because the funds are not processed immediately. I don't see how that us fair on me when I make purchases with sufficient funds in my account. This does not happen with my other bank. This is daylight ******* and it's really annoying me now because it's the second time it's happening this year. The first time it happened, I let it slide. But it did make me use the account less because I can't trust the bank to keep my money safe. I've had an incident where I was blocked from using funds in my account for no reason I was made aware off too. I have zero trust and confidence in Standard Bank.
