Woolworths Online shopping and App is the worst experience of all online shopping options

The Woolworths App for food home deliveries is just awful, the online web option is not much better. So clunky, illogical and completely designed to drive one to tears, especially when trying to send someone a birthday surprise cake delivery. Tried 5 times and each time got error messages and "incomplete" statuses. Tried phoning the contact centre which was a complete waste of time as was put on hold and then cut off. On the day of the delivery was surprised to see 2 identical orders for the same address out for delivery. Phoned contact centre again and was told that the recipient should just accept one of them and send the other back to the store. So much for the birthday surprise! That was done but it did not stop Woolworths taking payment for both orders. More contact centre calls, a ref number later I still do not know what is happening, which order was actually received, which was returned and when I will receive the refund.
