Extreme credit charges

<p>standard bank is ripping people off their hard earned money. On the 11th of May. I noticed that almost a R1000 was gone from my credit card, I went to the branch in Old Mutual PineLands to get clarity and it turns out that my bank charges have been over R750 a month for the past 3 months. There is something they have been charging me for called Finance charge R260 and Cash Finance Charges R380 and R145 for something I don't know. And today the last knock last night after I used my credit card my balance was R2070 and this morning I woke up with a balance of R0.00. Standard Bank can't do this. </p>
