Woolworths online

I ordered online and they didn't deliver on the day they promised, they instead delivered the following day at the wrong time and they debited my account twice. This was the worst online service I have ever received, because they would not even give me the option to pay on delivery and now I know why. I called the customer service and they said my money would be reversed in 24 hours. It has been more than 24 hours and no one has even contacted me.
