Woolworths Online incapable of delivery after 18 days

I've recently ordered a waistcoat for my wedding from Woolworths Online on the 9th of July 2019, which was scheduled for delivery on the 13th of July. The order was never delivered. I was assured that I will be contacted to reschedule the delivery, but never was. An attempt was made to deliver the item at a date when I was not available, and had to be rescheduled again. I was again assured that I will be contacted, but never was. After contacting customer care, a date of 24 July was agreed upon for delivery. Again the item was not delivered. After making multiple queries via email, to which I haven't received a single response, I phoned the customer care line. I was then informed that the item I have paid for has been returned to the store, and it will not be delivered by the 27th of July (18 days after placing the order. My wedding day.) After more than two weeks of non-delivery I had to cancel the order as it will not reach me in time.
