Reliance Trends — non receipt of online purchased items

My order number is tr06178270. It includes 5 items (Shipments). I received only two of them. My order date is june 9 2018. When i track the order it shows "we expect to deliver your order by 23 june 2018." the respective shipments shows the status of confirmed. I can't track each of them individually. This much delay in delivery gives a bad impression.
