Bad online store

I placed on online order 3 July, 3 items. All 3 items showed as IN STOCK. After payment I was informed there in not stock, I must wait. 28 July the order was updated with READY FOR DELIVERY. The courier guy showed up at my home 29 July with only 2 items. Seriously, almost 1 months later and they cannot send the full order - 3 items. Shocking online store, bad.
