Transaction pending

I went to Woolworths in Vincent park on Friday to buy groceries using my store card. After the items were billed the cashier said the transaction did not go through, since I had a lower balance in my card. I then queried that since I knew how much I had on my account. She then refered me to a client service consultant. The Client service consultant had to call the call centre to find out what went wrong only to find out the transaction did go through but it was pending so it needed to be reversed. I was told to wait for few minutes so it can be reversed. Fortunately after few minutes it had been reversed. The Cashier made another error, so the transaction did not go through again. I was then told to wait again.I ended up using my money that I did not budget for. <br> After the customer service consultant took my number and said she would call me in few minutes to tell me the funds have cleared. She did not call me, on Saturday the 11 July, I went there again I was then told again it will reflect on a weekday which will be Monday the 13 July. on Monday today I went there again to purchase something with the hope that they reflect but unfortunately not. I was told again to wait.
