Woolworths Dash delivery poor service!

Very very poor Dash Delivery service! I've placed an order for Mother's Day gifts to be delivered to my mother yesterday. No delivery took place yet, yet I've been invoiced and the delivery marked as delivered on their system. I've been calling multiple times only to be referred from one person to another who are all unable to provide me with answers or a resolve. Their provided contact number for Dash delivery enquiries are ineffective, agent straight away tells you 'sorry for the inconvenience but I will not be able to assist, please provide a contact number and we'll get back to you'...third time now. Extremely disappointing for a Woolworths! Seeing as I've just lost money on Woolworths, you've just lost a long-standing loyal customer
