Terrible Online Service

I ordered R900+ from Woolworths online with a delivery date a week later than the order - which was understood and accepted. However, when delivered only R335 of the original order was delivered and I therefore requested a pick up of all the goods which happened on the same day. There was no point in having the gravy but no meat to put it on. There was no notice prior to delivery that my delivery could not be complete (to less than 60% undeliverable). However what is worse is that the money was taken from my account and despite numerous phone calls and emails I have yet to have a response. Now nearly a month since the event and no sign of my funds being refunded. I am really disappointed with Woolworths and would like someone to respond.
