Useless ***** department blocking my card without my permission

I have some history with standard bank, I won't lie I really hate this bank, an unauthorized Uber purchase was made on my account I reported it but through enquiring not instruction, however without being informed the ***** department decided to block my card, I realize this incompetence when I'm at a filling station, imagine the embarrassment when my card declined but I see money in my account, I am told to wait for 5 to 7 days, I even explained to the person behind the email that I am on deployment and I cannot afford to have my card blocked and went through and blocked it anyway, I won't even get a refund for the *****ulent purchase but they still have the nerve to block my card, I am so annoyed with this bank that I even wanna settle this VAF and run far away from this useless bank, I've had enough!!!!
