No communication

I placed and paid for my online order with yuppiechef on 6 June 2018 at 08:55. I asked for the order to be delivered to my nearest Postnet. The system said I would get an sms when the package arrived at said Postnet. On 6 June at 3:45pm I got an email saying my order was on it's way. That is the last contact I had from Yuppichef. Yesterday (11 June) when I got to work I logged in to check the status of my order. The system did now show the order number. I emailed, being concerned with the situation and got a reply back at 3:59pm saying my package was at Postnet. My questions are: 1. Why did the order not show up in my order history for me to track it? 2. Why no contact from Yuppichef to say package had been delivered? 3. Why no sms to say package had arrived? Why must I as the customer run after you? I must say I was not impressed.
