Credit Card

Hi <br> Im very confused about the credit card of woolworth on the 14 September 15 I was having the balance of R2500 on my credit card than I left with a balance of R2056.00 than on the 22 September 15 I recieved an sms saying that my balance is R1695.00 but I did do a withdrawal and its not a first time this thing happened.I'm very upset with this and I'm planning to close all the account for woolworth that I have.<br> When u call them on their call centre you wait an hour before I'm fedup with them <br>
