Cancelled my parcel deivery

Ordered a product on 22 May 2026 and they indicated that delivery will take place on 1 June 2026, which I was happy with and thus waiting for 1 June to arrive. On Saturday 30 May, I get a whatsapp from an unknown number, letting me know he is at the gate to deliver a parcel. Since I have placed a stationary order a week before for delivery 30 May, and then cancelled that, I told the driver that the order was cancelled. This morning, all excited about the product to be delivered to me on 1 June, I checked the tracking of it...only to find out that the delivery was cancelled on Saturday and send back. Why would you say you will deliver on 1 June and then rock up 2 days before that????? If you had told me you will deliver on 30 May instead of 1 June, I would have been happy to take collection of the order.
