ZARA online - shocking delivery service

How can it be that in our times of online shopping that a company can take over a week to deliver a garments by courier service?

We ordered garments over a week ago from ZARA and got a delivery date for this week Wednesday or Thursday. The tracking indicator showed that the items had been handed over to the courier service, but on the day of delivery we then received an email that delivery was postponed to next week Monday!

How is such poor communication possible? Never mind poor logistics? The items were not out of stock when we ordered them? And worst of all the birthday party for which the garments were ordered is on Saturday! So we receiving the goods 4 days after the given delivery date.

That’s just shocking service. Pull up your socks ZARA.
