Disgusted Woolworths Customer

I am extremely upset with Woolworths and the treatment I got this morning. I have made an online order on the 28th and I had to put in my bank pin thereafter the money was deducted immediately, yesterday when I wanted to make a payment at a supplier I had insufficient funds due to Woolworths deducting another amount from my account without authorization. When I phoned this morning I was told the first amount will be reversed into my bank account, but that doesn't give them the right to deduct another amount that differs from the first without my consent. Secondly I specifically asked not for substitutions and now I am told I said they could substitute. No compensation for my extra banking fees due to double deduction No compensation for there error. Extreme Woolies Fan went to Extremely disgusted in the way they handled this error. My thinking is do Customers really matter to Woolies or is it all about making the money :-(
