de*****ed, humiliated, inconvenienced by ***** division?

I do a Std bank credit card transaction (small in relation to my other transactions) at wish.com. I received a sms that my card has been suspended. I need to call ***** division. My ref nr and phone nr was the same nr. I phoned them, eventually I was told that they suspected a ********** transaction (for no reason at all) and declined it as well as suspended my account. I reactivated the card. I was told that the transaction cannot be approved after it was declined and that I had to do another (new) transaction/purchase if I still want the item. I did this. Then I received confirmations that both transactions went through. Now.. the Bank/Card division tell me there is nothing they can do. One of the transactions cannot be reversed. eventually I had to hold again and was simply cut off. In the past I had to spend a night at a petrol station in another province (on my way to an to do an exhibition!!) My only payment method was this card which was in credit. Same thing ... it was suspended because they suspected a ********** transaction. With larger transactions with a higher risk of being ********** there is never an issue.
