Woolworths customer service disgrace

I have to post about my experience I had today so that Woolworths and other shoppers are aware of what goes on... I purchased a clothing item on the sale on Tuesday from the Woolworths store in Hyde Park. Once I checked my slip I noticed that I was charged full price and not the sale amount. (Woolworths first error) I then returned to the store the following day to return my jacket and bought it back at the discounted price. Today after looking at my bank account I noticed that instead of refunding me Woolworths had charged me! So I went to the Woolworths store in Melrose Arch, waited for the manger who told me I had to return to Hyde Park. I returned to Hyde Park, paying petrol and parking and wasting my time once again, only for Woolworths to deny that it was their mistake. They claimed it was the banks error. So off I went to the bank.. I spent time at the bank, who proved that it was an error on the side of Woolworths and they reversed the transaction. So I now had to return to Woolworths thinking it will be quick and I will get my money back....well I was wrong!!! That took another 30 minutes or longer until I was finally refunded what was
