Unknown withdrawal from my account

I am so disappointed at Standard Bank, A year ago there was an unknown withdrawal of R500 on my account, I reported the matter and got the worst service from the consultant who imp**** that the withdrawal was done by myself or my husband, after fighting and escalating the matter Standard bank refunded me and closed my savings account and opened a cheque account, Last night(01/12/2019) at 23:30 pm R800 was withdrawn from my account, not by myself however my card was with me so was my husband, I rarely do withdrawals because of these ****s, I prefer instant cash withdrawals , I got an sms today -02/12/2019 morning of the withdrawal and reported the matter telephonically , I spoke to Patrick Zwane who advised that he has cancelled the old card and ordered the new one and has opened a case and gave me Ref number( ********** ), said Standard bank will get back to me within 24-48 hours with feedback as they still need to investigate internally on their side. I need this money and I must now wait for my money, why was the matter not dealt with properly the first time last year? How much are they going to withdraw next time on my account? Why is my money not same with my bank? This is frustrating
