Shocking service

Shocking service. Ordered item on 16th April and on the site says delivery on 24th April. I called yesterday to confirm all in order for delivery only to be told they have not let the seller know. They promise to escalate. Call this morning to find out what is going on, only to be told that the Seller has not been updated with my order. Makro customer service tells me they just put a delivery date on the site but its "inaccurate". Unacceptable.. I could have purchased this item anywhere and had it the next day. Not impressed and will probably never shop there again.
